Jack collects all his neighbors' recycling and sorts out the cans and bottles to return for the deposit. He gets 10 cents per bottle and 5 cents per can.

Question: If he recycled 80 bottles and made $15, how many cans did he recycle?
Answer: First find the total amount Jack earned from the bottles: $0.10/bottle * 80 bottles = $<<0.10*80=8.00>>8.00
Then subtract that amount from his total earnings to find the amount he earned from cans: $15.00 - $8.00 = $<<15-8=7.00>>7.00
Then divide his total earnings from cans by his earnings per can to find the number of cans he recycled: $7.00 / $0.05/can = <<7/0.05=140>>140 cans

Out of 480 employees, 10% got a salary increase while 20% got a travel allowance increase.

Question: How many employees did not get any increase?
Answer: 480 x 10/100 = <<480*10/100=48>>48 employees got a salary increase.
480 x 20/100 = <<480*20/100=96>>96 employees got a travel allowance increase.
So a total of 48 + 96 = <<48+96=144>>144 employees got an increase.
Therefore, 480 - 144 = <<480-144=336>>336 employees did not get any increase.

Anna can read 1 page in 1 minute. Carole can read as fast as Anna but at half the speed of Brianna.

Question: How long does it take Brianna to read a 100-page book?
Answer: If Anna can read 1 page in 1 minute, then her speed is 1/1 = <<1/1=1>>1 page per min
If Carole can read at Anna's same speed then her speed is also 1 page per min
If Carole is only half the speed of Brianna, then that means Brianna is twice as fast as Carole, so 2 * 1 page per min = <<1*2=2>>2 pages per min
If a book is 100 pages long and Brianna can read 2 pages per minute, then it will take her 100/2 = <<100/2=50>>50 minutes to read the book

Lillian went out to forage for mushrooms with her handy guidebook. She found 32 mushrooms and used her guidebook to identify which ones were poisonous and which were safe to eat. In the end, she had 9 mushrooms she could safely eat for dinner. Of the rest, she identified twice the amount she ate as poisonous, and a remaining bunch she was uncertain about.

Question: How many mushrooms was she uncertain were safe or poisonous?
Answer: Lillian found 9 of the mushrooms were safe, so there were 32 - 9 = <<32-9=23>>23 that she found poisonous or uncertain.
She knew twice the amount she ate were poisonous, so she found 9 * 2 = <<9*2=18>>18 poisonous mushrooms.
Thus, she was uncertain about 23 - 18 = <<23-18=5>>5 mushrooms.

Barry wants to make a huge salad using only cucumbers and tomatoes. He will use a total of 280 pieces of vegetables.

Question: If there are thrice as many tomatoes as cucumbers, how many cucumbers will be used in the salad?
Answer: Let c be the number of cucumbers and t the number of tomatoes.
The total is the sum of the number of cucumbers and that of tomatoes, which is c + t = 280 piece of vegetables
Since there are thrice as many tomatoes as cucumbers, this means c =t/3
Therefore 3*c = t.
The sum will therefore be c + 3*c = 280 pieces of vegetables
This means that 4*c = 280 vegetables
Therefore c = 280/4 = <<280/4=70>>70 cucumbers.

Blake wants to spend his Friday making milkshakes for his family. He knows that he needs 4 ounces of milk and 12 ounces of ice cream for each milkshake.

Question: If he has 72 ounces of milk and 192 ounces of ice cream, how much milk will be left over when he is done?
Answer: He has enough milk to make 18 milkshakes because 72 / 4 = <<72/4=18>>18
He has enough ice cream to make 16 milkshakes because 192 / 12 = <<192/12=16>>16
He can only make 16 milkshakes because 16 < 18
He will use 64 ounces of milk because 16 x 4 = <<16*4=64>>64
He will have 8 ounces of milk left because 72 - 64 = <<72-64=8>>8

Jill runs a business breeding llamas. Nine of her llamas got pregnant with 1 calf, and 5 of them got pregnant with twins. After they give birth, Jill traded 8 of the calves for 2 new adult llamas. Then she sells 1/3 of her herd at the market.

Question: How many total llamas  (calves and adults) does Jill have now?
Answer: The number of calves that will be born as twins is 5 * 2 = <<5*2=10>>10 calves.
The total number of adults and calves before the trade is 9 + 5 + 9 + 10 = <<9+5+9+10=33>>33.
Jill had 33 - 8 = <<33-8=25>>25 left for trading 8 of the claves.
But, she got 2 adult llamas in return, so she now has a total of 25 + 2 = <<25+2=27>>27 llamas.
She then sold 27 / 3 = <<27/3=9>>9 llamas in the market.
So, Jill has 27 - 9 = <<27-9=18>>18 llamas now.

Isabella has three times as many green houses as yellow houses. She also has 40 fewer yellow houses than red houses.

Question: If she has 90 green houses, how many of her houses are not yellow?
Answer: If the number of green houses is three times the number of yellow houses, and there are 90 green houses, then there are 90/3 = 30 yellow houses.
She also has 40 fewer yellow houses than blue houses, meaning there are 30+40 = <<30+40=70>>70 blue houses.
The number of houses that are not yellow is 70 blue houses +90 green houses = <<70+90=160>>160

Louis is making himself a velvet suit for a formal event. The velvet fabric he chose was $24 per yard. He bought a pattern for $15, and two spools of silver thread for $3 each.

Question: If he spent $141 for the pattern, thread, and fabric, how many yards of fabric did he buy?
Answer: Let V be the number of yards of velvet fabric Louis bought.
The silver thread cost 2 * 3 = $<<2*3=6>>6.
He spent 24V + 15 + 6 = $141 on the suit.
The fabric cost 24V = 141 - 15 - 6 = $120.

Frank spent 1/5 of his money to buy groceries. He then spent 1/4 of the remaining money to buy a magazine.

Question: If he had $360 left in his wallet, how much money did he have at first?
Answer: Let X be the money Frank had originally.
Frank spent 1/5*X on groceries.
Frank spent 1/4*(X-1/5*X) on a magazine.
Frank has X - 1/5*X - 1/4*(X-1/5*X) = $360 left in his wallet.
Multiplying through the parentheses, we get X - 1/5*X - 1/4*X + 1/20*X = $360.
Combining like terms, we get 12/20*X = $360.
Dividing both sides by 12/20, we get X = $600.

The rim of a standard basketball hoop is 10 feet above the ground. Additionally, most experts will say that a player must be able to reach at least 6 inches above the rim to dunk a basketball. Suppose a basketball player is 6 feet tall and can reach 22 inches above their head using the wingspan of their arms.

Question: How high must this player be able to jump to reach 6 inches above the rim to dunk a basketball?
Answer: In inches, the height of the rim is 10*12 = <<10*12=120>>120 inches.
Thus, the height that the player needs to be able to reach is 120 + 6 = <<120+6=126>>126 inches.
Without jumping, the player can reach their height plus an additional 22 inches, or a total of 6*12 + 22 = <<6*12+22=94>>94 inches.
Therefore, the player needs to jump 126 - 94 = <<126-94=32>>32 inches to reach the height required to dunk a basketball.

Toby held a garage sale to raise money to support friends who have lost their jobs. Of all the items that he sold during the garage sale, three of the items he sold made up 75% of the total amount of sales money he earned. He sold a treadmill for $100, a chest of drawers for half as much as he made for selling the treadmill, and he sold a television for three times what he earned for selling the treadmill.

Question: What is the total sum of money, in dollars, that Toby made at the garage sale?
Answer: The chest of drawers sold for half as much as the treadmill, for a price of $100/2= $<<100/2=50>>50.
The television sold for three times what he earned for the treadmill, for a price of $100*3= $<<100*3=300>>300.
For the three items, he raised $100+$50+$300 = $<<100+50+300=450>>450.
If $450 is 75% of the total sum of money that Toby made at the garage sale, then the total amount is $450 / (75/100) = $600.

Elsa started the day with 40 marbles. At breakfast, she lost 3 marbles while playing. At lunchtime, she gave her best friend Susie 5 marbles. In the afternoon, Elsa's mom bought her a new bag with 12 marbles. Susie came back and gave Elsa twice as many marbles as she received at lunch.

Question: How many marbles did Elsa end the day with?
Answer: Elsa had 40 marbles - 3 - 5 = <<40-3-5=32>>32 marbles.
Elsa then gained 12 marbles + 32 = <<12+32=44>>44 marbles.
At dinner Elsa received 2 * 5 marbles from Susie = <<2*5=10>>10 marbles.
In total Elsa had 44 marbles + 10 = <<44+10=54>>54 marbles.

Bert has a garden shop. He buys his products in a warehouse and sells them for $10 more in his shop. From each sale, he has to pay 10% of the value in tax. One day a client came to his shop and bought a barrel for $90.

Question: How Much money did Bert make on this sale?
Answer: First, we need to know how much Bert paid for the barrel in the warehouse, and that is 90 - 10 = $<<90-10=80>>80.
The tax from the sale stands at 10/100 * 90 = $<<10/100*90=9>>9.
That means Bert earned 90 - 9 - 80 = $<<90-9-80=1>>1 on the sale.
