Chloe and Max played Mario Kart together. The ratio of Chloe’s wins to Max’s wins is 8:3. Chloe won 24 times.

Question: How many times did Max win?
Answer: We are trying to figure out how many times Max won at Mario Kart, so we'll call that number Y.
We know the ratio of Chloe’s wins to Max’s wins is 8/3, so 8/3 = 24/Y.
Next, we will multiply to find the cross-products. 8 x Y = 3 x 24 or 8Y = 72.
We want to get figure out Y, so we need to get it by itself by dividing by 8, like this: 8Y / 8 = 72 / 8.
Y = <<9=9>>9, so Max won 9 times.

Kenneth spent 10% of this earnings this week on a new joystick.

Question: If he is left with $405, how much were his earnings?
Answer: Since Kenneth spent 10%, then he is left with 100% - 10% = 90% of his earnings.
Since 90% of his earnings is worth $405, then 1% of his earnings is $405/90 = $<<405/90=4.50>>4.50.
Hence, Kenneth's earnings is $4.50 x 100 = $<<450=450>>450.

Bill composes 20 total math questions for money. Ryan composes twice as many problems as Bill, and Frank composes 3 times as many as Ryan.

Question: Assuming each person has to compose 4 different types of math problems in equal proportion out of the total amount, how many problems of each type does Frank compose?
Answer: Since Ryan composes twice as many problems as Bill's total of 20, this means Ryan composes 20*2=<<20*2=40>>40 problems
Frank composes 3 times as many as Ryan does, so this means Frank composes 40*3=<<40*3=120>>120 problems.
Since Frank needs to submit 4 types of problems in equal proportion out of his total, this means he needs to make 120/4= <<120/4=30>>30 problems of each type.

Brad wanted to set up a lemonade stand to earn some money. Every gallon of lemonade would yield 16 glasses. He figured it would cost him $3.50 to make every gallon of lemonade. He made 2 gallons to sell and decided he would sell each glass for $1.00  He drank 5 glasses while sitting in his stand. He sold all but 6 glasses of lemonade.

Question: How much net profit did Brad earn?
Answer: He made 2 gallons and each gallon had 16 glasses so 2*16 = <<2*16=32>>32 glasses
He drank 5 glasses and had 6 left over which means he would not earn money on 5+6 = <<5+6=11>>11 glasses
The total revenue would come from 32-11 = <<32-11=21>>21 glasses
Each gallon cost $3.50 to make so the total cost was 2*3.50 = $<<2*3.50=7.00>>7.00
He sold 21 glasses at $1.00 per glass for a total of 1*21 = $<<21*1=21.00>>21.00
When you take his earnings of $21.00 and subtract the cost of $7.00 his total net profit was 21-7 = $<<21-7=14.00>>14.00

Markus is twice the age of his son, and Markus's son is twice the age of Markus's grandson.

Question: If the sum of the ages of Markus, his son, and his grandson is 140 years, then how many years old is Markus's grandson?
Answer: Let "x" be the age of Markus's grandson.
If Markus's son is twice the age of Markus's grandson, then Markus's son is 2*x.
If Markus is twice the age of his son, then Markus is 2*2*x.
Therefore, if the sum of the ages of Markus, his son, and his grandson is 140 years, then x+(2*x)+(2*2*x)=140 years.
Simplifying the equation, we see that 7*x=140 years.
Therefore, the age of Markus's grandson is x=20 years old.

Belinda’s dog is missing, so she made 200 flyers to distribute around town with the help of her friends. Ryan passed out 42 flyers, Alyssa passed out 67, Scott passed out 51 and Belinda passed out the rest.

Question: What percentage of the flyers did Belinda pass out?
Answer: The total number of flyers Belinda’s friends passed out was 42 by Ryan + 67 by Alyssa + 51 by Scott = <<42+67+51=160>>160 flyers.
Belinda passed out 200 total flyers – 160 flyers passed out by friends = <<200-160=40>>40 flyers.
To express this as a decimal, divide Belinda’s 40 flyers / 200 total flyers = <<40/200=0.20>>0.20.
Belinda passed out 0.20 x 100% = 20% of the flyers.

Rookie police officers have to buy duty shoes at the full price of $85, but officers who have served at least a year get a 20% discount. Officers who have served at least three years get an additional 25% off the discounted price.

Question: How much does an officer who has served at least three years have to pay for shoes?
Answer: Cops that served a year pay $85 * 0.2 = $<<85*0.2=17>>17 less.
Cops that served a year pay $85 - $17 = $<<85-17=68>>68.
Cops that served at least 3 years get a $68 * 0.25 = $<<68*0.25=17>>17 discount.
Cops that served at least 3 years pay $68 - $17 = $<<68-17=51>>51 for shoes.

Keanu was surfing towards the shore at a speed of 20 miles per hour. A shark was swimming alongside him, riding the same wave, when it doubled its speed and moved away from Keanu. There was a pilot fish swimming alongside Keanu and the shark, and when the shark increased its speed, the pilot fish also increased its speed and moved away from Keanu, but only increasing its speed by half as much as the shark had increased its speed by.

Question: What speed, in miles per hour, was the pilot fish swimming when it moved away from Keanu?
Answer: The shark went from 20 miles per hour to a speed of 2*20=40 miles per hour.
The shark increased its speed by 40-20=<<40-20=20>>20 miles per hour.
Half of the shark's increase in speed is 20/2=<<20/2=10>>10 miles per hour.
Thus the pilot fish had increased its speed to 20+10=<<20+10=30>>30 miles per hour.

Damien collects glasses for a hobby and decides he wants to put them in display cupboards. His tall cupboard can hold 20 glasses, his wide cupboard can hold twice as many, and his narrow cupboard can hold 15 glasses with the glasses divided equally among the three shelves. As Damien is putting glasses in the narrow cupboard, he accidentally breaks one of the shelves.

Question: If all of the cupboards are full, how many glasses are currently being displayed?
Answer: The wide cupboard holds twice as many glasses as the tall cupboard, amounting to 20 * 2 = <<20*2=40>>40 glasses.
Each of the shelves in the narrow cupboard holds 15 / 3 = <<15/3=5>>5 glasses.
Since a shelf was broken, a narrow cupboard now holds only 15 – 5 = <<15-5=10>>10 glasses.
In total, there are 20 + 40 + 10 = <<20+40+10=70>>70 glasses.

Marissa is serving her kids lunch. Each kid gets a burger with 400 calories and 5 carrot sticks with 20 calories each, and some cookies with 50 calories each. Marissa wants each kid to eat a total of 750 calories for lunch.

Question: How many cookies does each kid get?
Answer: First figure out how many total calories come from the carrots by multiplying the calories per carrot by the number of carrots: 20 calories/carrot * 5 carrots = <<20*5=100>>100 calories
Then subtract the calories the kids have already eaten from the goal number of calories to find out how many more total calories they should eat: 750 calories - 400 calories - 100 calories = <<750-400-100=250>>250 calories
Then divide the total number of calories by the calories per cookie to find the number of cookies each kid gets: 250 calories / 50 calories/cookie = <<250/50=5>>5 cookies

Nancy and Rose are making bracelets, and there are eight beads in each bracelet. Nancy has 40 metal beads and 20 more pearl beads. Rose has 20 crystal beads and twice as many stone beads as crystal beads.

Question: How many bracelets can Nancy and Rose make?
Answer: Nancy has 40 + 20 = <<40+20=60>>60 pearl beads.
So, Nancy has a total of 40 + 60 = <<40+60=100>>100 beads.
Rose has 2 x 20 = <<2*20=40>>40 stone beads.
So, Rose has 20 + 40 = <<20+40=60>>60 beads.
Thus, Nancy and Rose have 100 + 60 = <<100+60=160>>160 beads altogether.
Therefore, they can make 160/8 = <<160/8=20>>20 bracelets.

A farmer has 46 chickens. Each chicken gives him 6 eggs a week.

Question: If he sells a dozen eggs for $3, how much money would he make in 8 weeks?
Answer: The farmer gets 46 x 6 = <<46*6=276>>276 eggs a week.
That gives him 276/12 = <<276/12=23>>23 dozen eggs.
In one week, he makes 23 x 3 = $<<23*3=69>>69
In 8 weeks, he makes $69 x 8 = $<<69*8=552>>552

Trevor is currently 11 years old and his older brother is 20 years old.

Question: How old will Trevor be when his older brother is three times as old as Trevor is now?
Answer: When Trevor is 11, his older brother will be 11 x 3 = <<11*3=33>>33 years old.
Trevor’s older brother is 20 - 11 = <<20-11=9>>9 years older than Trevor.
Since Trevor is 9 years younger, Trevor will be 33 - 9 = <<33-9=24>>24 years old.

Janet buys 45-pound containers of cat litter for $21 each.

Question: If her cat litter box holds 15 pounds of cat litter, and she changes out the litter weekly, how much will it cost, in dollars, for her to buy enough litter to last 210 days?
Answer: If she changes the box weekly, then in 210 days, she will change the box 210/7=<<210/7=30>>30 times.
At 15 pounds of litter for every box change, she will require 30*15=<<30*15=450>>450 pounds of cat litter in 210 days.
If she buys 45-pound containers, then for 450 pounds she will need to buy 450/45=<<450/45=10>>10 containers of litter.
At $21 per container, to buy enough cat litter for 210 days, it will cost 10 * $21 = $210
