Lorie has 2 pieces of $100 bills. He requested to change one piece of the $100 bills into $50 bills. Half of the remaining $100 bill is changed to $10 bills while the rest is changed to $5 bills.

Question: How many pieces of bills will she have?
Answer: There will be $100/$50 = <<100/50=2>>2 pieces of $50 when $100 is changed to $50 bills.
Half of $100 is $100/2 = $<<100/2=50>>50.
So there will be $50/$10 = <<50/10=5>>5 pieces of $10 when $50 is changed to $10 bills.
The remaining $50 will be changed to $5 bills so there will be $50/$5 = <<50/5=10>>10 pieces of $5 bills.
So in total, Lorie will have 2 $50 bills + 5 $10 bills + 10 $5 bills = <<2+5+10=17>>17 pieces of bills.

The school is hosting a race after school. The winner is the person who runs the most laps around the school in 12 minutes. One lap around the school is 100 meters. The winner is awarded a gift certificate equal to $3.5 for every one hundred meters they run. The winner runs 24 laps around the school.

Question: On average, how much did they earn per minute?
Answer: They ran 2,400 meters because 24 laps x 100 m/lap = <<24*100=2400>>2400 m
They ran 200 meters per minute because 2400 m / 12 min = <<2400/12=200>>200 m/min
For every minute they ran they earned an average of $7 because $3.5/100m x 200 m/min = $<<3.5/100*200=7>>7/min

Milly and Floretta are having a water balloon fight in their garden. They use 3 packs of their own water balloons and also use 2 packs of a neighbor’s water balloons. Each pack of water balloons contains 6 balloons. Milly and Floretta fill all of the balloons then split them evenly, but Milly takes an extra 7 balloons when Floretta isn't looking.

Question: How many water balloons is Floretta left with?
Answer: Milly and Floretta have a total of 3 packs of their own water balloons + 2 packs of the neighbor’s water balloons = <<3+2=5>>5 packs of water balloons.
So there is a total of 5 packs of water balloons * 6 balloons per pack of water balloons = <<5*6=30>>30 water balloons available.
As they split them evenly, they each have 30 water balloons / 2 = <<30/2=15>>15 water balloons.
After Milly steals some balloons, Floretta is left with 15 – 7 = <<15-7=8>>8 water balloons.

Two runners are competing in a 10-mile race. The first runs at an average pace of 8 minutes per mile, while the second runs at an average pace of 7 minutes per mile. After 56 minutes, the second runner stops for a drink of water.

Question: For how many minutes could the second runner remain stopped before the first runner catches up with him?
Answer: After 56 minutes, the second runner has traveled 56/7 = <<56/7=8>>8 miles.
Similarly, the first runner has traveled 56/8 = <<56/8=7>>7 miles.
Therefore, the two runners are 8 - 7 = <<8-7=1>>1 mile apart when the second runner stops.
Thus, the second runner can stop for a maximum of 8 minutes, which is the amount of time it takes the first runner to travel 1 mile.

Lucy has been trying new recipes and wants to make sure she keeps the cupboard stocked with ingredients. She had a 500g bag of flour in the cupboard at the start of the week. She used 240g when she baked cookies on Tuesday, and accidentally spilled half of what was left when she was putting the flour away.

Question: If Lucy wants a full bag of flour in the cupboard, how much flour does she need to buy, in grams?
Answer: After baking cookies, Lucy had 500 – 240 = <<500-240=260>>260g of flour left.
She accidentally spilled half of this, which means she had 260 * 0.5 = <<260*0.5=130>>130g of flour left.
She therefore needs 500 – 130 = <<500-130=370>>370g of flour.

John is trying to save money by buying cheap calorie-dense food. He can buy 10 burritos for $6 that have 120 calories each. He could also buy 5 burgers that are 400 calories each for $8.

Question: How many more calories per dollar does he get from the burgers?
Answer: The burritos have 10*120=<<10*120=1200>>1200 calories
That means he gets 1200/6=<<1200/6=200>>200 calories per dollar
The burgers get 5*400=<<5*400=2000>>2000 calories
So he gets 2000/8=<<2000/8=250>>250 calories per dollar
So he gets 250-200=<<250-200=50>>50 more calories per dollar from the burgers

Gary has 6 pounds of flour. He will use 4 pounds of flour to make cakes which require 0.5 pounds of flour each. The remaining 2 pounds of flour will be used to bake cupcakes, which require 1/5 pounds of flour. He plans to sell the cakes for $2.5 each and the cupcakes for $1 each in the school's bake sale.

Question: How much will Gary earn?
Answer: Gary can bake 4/0.5 = <<4/0.5=8>>8 cakes from the 4 pounds of flour.
He can bake 2/ 1/5 = 10 cupcakes from the 2 pounds of flour.
So, he will earn $2.5 x 8 = $<<2.5*8=20>>20 from the cakes.
Hence, Gary will earn a total of $20 + $10 = $<<30=30>>30 from baking 8 cakes and 10 cupcakes.

Hannah is trying to figure out how much she'll get paid this week. She makes $30/hour and works 18 hours per week. Her pay is docked $5 each time she's late.

Question: If she was late 3 times this week, how much does she get paid?
Answer: Hannah's total earnings are 18 hours * $30/hour = $<<18*30=540>>540 a week.
Her pay was docked because she was late 3 times, so 3 times * $5 per time = $<<3*5=15>>15 were docked.
She gets paid $540 - $15 = $<<540-15=525>>525 at the end of the week.

The list included a carton of milk for $4.00, a loaf of bread for $3.50, a box of laundry detergent for $10.25 and 2 pounds of bananas that were $0.75 per pound. Her mom also gave her a coupon for $1.25 off of the laundry detergent. At checkout, the clerk told her the milk was 1/2 off today.

Question: How much money did Josie have left over after she bought all of the groceries?
Answer: The milk cost $4.00 but was on sale for 1/2 off so 4*.50 = $<<4*.50=2.00>>2.00
She bought 2 pounds of bananas at $0.75 per pound so 2 *.75 = $<<2*0.75=1.50>>1.50
She had a $1.25 coupon off of laundry detergent so 10.25 - 1.25 = $<<10.25-1.25=9.00>>9.00
When you add all of her purchases together then 2 + 1.50 +3.50 + 9.00 = $<<2+1.50+3.50+9=16.00>>16.00
She paid with a $20 bill so 20-16 = $<<20-16=4>>4 left over

At the burger hut, you can buy a burger for $5, french fries for $3, and a soft drink for $3. If you order a special burger meal, you get all 3 of these food items for $9.50. A kid’s burger is $3, a kid’s french fries are $2, and a kid's juice box is $2. They also have a kids meal of all 3 kids' food items for $5. Mr. Parker buys 2 burger meals for his wife and himself. He also buys 2 burger meals and 2 kid's meals for his 4 children.

Question: How much money does Mr. Parker save by buying the 6 meals versus buying the individual food items?
Answer: To buy regular food items individually, they cost $5 + $3 + $3 = $<<5+3+3=11>>11.
To buy kids food items individually, they cost $3 + $2 + $2 = $<<3+2+2=7>>7.
If you buy the special burger meal, you save $11 - $9.50 = $<<11-9.5=1.50>>1.50.
If you buy the kid's meal, you save $7 - $5 = $<<7-5=2>>2.
Mr. Parker buys 4 special burger meals, bringing his discount to 4 x $1.50 = $<<4*1.50=6>>6.
He buys 2 kid's meals, bringing his discount to 2 x $2 = $<<2*2=4>>4.
The total savings for Mr. Parker is $6 + $4 = $<<6+4=10>>10.

A competition has racers competing on bicycles and tricycles to win a grand prize of $4000.

Question: If there are 40 people in the race, and 3/5 of them are riding on bicycles, how many wheels do the bicycles and tricycles in the race have combined?
Answer: If 3/5 of the people in the race are riding bicycles, their number is 3/5 * 40 people = <<3/5*40=24>>24 people
Since a bicycle has 2 wheels, and 24 people were riding on a bicycle each, the total number of bicycle wheels in the race is 2 wheels/bike * 24 bikes = <<2*24=48>>48 wheels
The number of racers on tricycles is 40 people - 24 people = <<40-24=16>>16 people
Since a tricycle has 3 wheels, and 16 people were riding on a tricycle each, the total number of tricycle wheels in the race is 3 wheels/trike * 16 trikes = <<3*16=48>>48 wheels
The combined total for bicycle and tricycle wheels in the race is 48 wheels + 48 wheels = <<48+48=96>>96 wheels

#### 168
Barney washes his kitchen towels once a week. He owns eighteen towels and uses two at a time that he changes to clean towels daily. He missed one week of laundry.

Question: How many days the following week will Barney not have clean towels?
Answer: Barney uses 2 clean towels every day, so he uses 2 * 7 = <<2*7=14>>14 towels a week.
He missed one week of laundry, so he would need 2 * 14 = <<2*14=28>>28 towels for 2 weeks.
He owns 18 towels, so he has 28 - 18 = <<28-18=10>>10 less than he needs.
Thus, Barney will not have clean towels on 10 / 2 = <<10/2=5>>5 days.

Carson needs to mow the lawn and plant some flowers. Carson has to mow 40 lines to cover the whole yard, and it takes him 2 minutes to mow one line. He also needs to plant 8 rows of flowers, each with 7 flowers, and it takes him half a minute to plant each flower.

Question: How many minutes will Carson spend gardening?
Answer: First find the total time Carson spends mowing: 40 lines * 2 minutes/line = <<40*2=80>>80 minutes
Then find the total number of flowers Carson plants: 8 rows * 7 flowers/row = <<8*7=56>>56 flowers
Then multiply that number by the time taken to plant each flower to find the total time spent planting flowers: .5 minutes/flower * 56 flowers = <<.5*56=28>>28 minutes
Finally, add that time to the time spent mowing to find the total time spent gardening: 28 minutes + 80 minutes = <<28+80=108>>108 minutes

Lyla, a grocery store owner, bought rice weighing 30 kg less than green beans, which weigh 10 kg more than sugar. While carrying the goods to the store, the bags fell down and 1/3 weight of the rice and 1/5 weight of sugar was lost.

Question: If the green beans weighed 60 kgs, then how much did the remaining stock weigh?
Answer: If rice weighed 30 kg less than the green beans, then the total rice weight is 60 kg - 30 kg = 30 kg
If the green beans weighed 10 kg more than sugar, then the total sugar weight is 60 kg - 10 kg = <<60-10=50>>50 kg
When 1/3 weight of rice was lost, the weight loss became 1/3*30 = <<1/3*30=10>>10kg
The weight of rice after the loss is 30 kg - 10 kg = <<30-10=20>>20 kg.
When 1/5 weight of sugar was lost, the lost weight was 1/5 * 50 kg = <<1/5*50=10>>10 kg
The weight of sugar after the loss is 50 kg - 10 kg = <<50-10=40>>40 kg.
The total weight for all the items is 40 kg + 20 kg + 60 kg = <<40+20+60=120>>120 kg

An old pirate wants to leave his treasure on an island. He has 3500 gold coins. He wants to spread this equally across 5 chests. Additionally, he will put a total of 500 silver coins and twice as many bronze coins as silver, all distributed equally across the chests.

Question: How many coins in total will be in each chest?
Answer: There will be 3500 gold coins / 5 chest= <<3500/5=700>>700 gold coins in every chest.
So, there will be 500 silver coins / 5 chests = <<500/5=100>>100 silver coins in each chest.
Then, the number of bronze coins is double the number of silver coins, so there are 2 * 500 = <<2*500=1000>>1000 bronze coins.
So there will be 1000 bronze coins / 5 chests = <<1000/5=200>>200 bronze coins in each chest.
Finally, the total number of coins in every chest will be 700 gold coins + 100 silver coins + 200 bronze coins = <<700+100+200=1000>>1000 coins.

UF got into the national championship. For them to get into the championship, they scored a total of 720 points during their previous 24 games. In the championship game, however, their opponent was much stronger than any other team they had previously gone against and they scored 2 points less than half as much as they had previously scored in each of the 24 games. Their opponent only lost by 2 points.

Question: How many points did their opponent score?
Answer: They scored an average of 720/24=<<720/24=30>>30 points in their previous games
Half that many would be 30/2=<<30/2=15>>15 points
So in the finals, they scored 15-2=<<15-2=13>>13 points
Their opponent thus scored 13-2=<<13-2=11>>11 points

George is about to celebrate his 25th birthday. Since his 15th birthday, he's been given a special $1 bill from his parents. They told him that on his 25th birthday, for every bill he still has, they will give him $1.5 in exchange. He spent 20% of his special bills.

Question: How much will he receive from his parents when he exchanges them?
Answer: He received 10 special bills because 25 - 15 = <<25-15=10>>10
He has 80% of them left because 100 - 20 = <<100-20=80>>80
He has 8 left because 10 x .8 = <<10*.8=8>>8
His parents will give her $12 for them because 8 x 1.5 = <<8*1.5=12>>12
