First find the total cost of the color cartridges: $32 / cartridge * 3 cartridges = $96. Then add the cost of the black - and - white cartridge to find the total cost: $96 + $27 = $123.
The answer: 123
Reverse engineering the question: To get the printer to work, Jerry needs to add a black-and-white cartridge and three color cartridges. If each color cartridge costs $32 and each black-and-white cartridge costs $27, how much does he pay total?


Reasoning and answer: Ravi has 6 + 2 = 8 quarters. He has also 8 + 4 = 12 dimes. A nickel is worth 5 cents so Ravi's nickels amount to 6 x 5 = 30 cents. A quarter is worth 25 cents so his quarters amount to 8 x 25 = 200 cents. A dime is worth 10 cents so his dimes amount to 12 x 10 = 120 cents. therefore, Ravi has 30 + 200 + 120 = 350 cents.
The answer: 350
What was the question?
Question: Ravi has some coins. He has 2 more quarters than nickels and 4 more dimes than quarters. If he has 6 nickels, how much money does he have?


3 feet are in 1 yard and her fence is 25 yards long so her fence is 3 * 25 = 75 feet long. At maturity these trees will measure 1.5 feet and she needs them to run along her 75 - foot fence so she needs 75 / 1.5 = 50 trees. The trees cost $8.00 apiece and she needs 50 so 8 * 50 = $400.00 worth of trees.
The answer: 400
Reverse engineering the question: Holly wants to plant a wall of privacy trees along her fence line. Her fence is 25 yards long. At maturity, the trees she wants to plant will measure 1.5 feet wide. Right now, these trees are on sale for $8.00 apiece. How much will it cost her to plant a row of the trees to run the length of her fence?


Reasoning and answer: She uses 3 ounces of beans per day because 2 x 1.5 = 3. She uses 21 ounces of beans per week because 7 x 3 = 21. She buys 2 bags of beans per week because 21 / 10.5 = 2. She spends $16 on the beans per week because 2 x 8 = 16. She spends $2 on the milk per week because 4 x (1 / 2) = 2. She spends $18 per week on her coffee because 16 + 2 = 18.
The answer: 18
What was the question?
Question: Maddie wants to see how much her mom spends on coffee each week. She makes herself 2 cups of coffee per day. Each cup has 1.5 ounces of coffee beans. A bag of coffee costs $8 and contains 10.5 ounces of beans. She uses 1/2 a gallon of milk per week. A gallon of milk costs $4. She doesn't add any sugar to the coffee. How much does she spend on her coffee per week?


Anya has 4 x 4 = 16 erasers. Thus, Anya has 16 - 4 = 12 more erasers than Andrea.
The answer: 12
Reverse engineering the question: Anya has 4 times as many erasers as Andrea. If Andrea has 4 erasers, how many more erasers does Anya have than Andrea?


There are 300 + 200 + 80 = 580 birds in total. Every day 20 + 8 + 5 = 33 birds are lost. After a week which is 7 days, 33 * 7 = 231 birds would be lost. There would be 580 - 231 = 349 birds left in the poultry.
The answer: 349
Reverse engineering the question:
A small poultry farm has 300 chickens, 200 turkeys and 80 guinea fowls. A strange, incurable disease hit the farm and every day the farmer lost 20 chickens, 8 turkeys and 5 guinea fowls. After a week, how many birds will be left in the poultry?
