Sandra's father gave her $4 * 2 = $8. So Sandra has in total $8 + $4 + $10 = $22. She wants 14 candies, so she is going to pay 14 candies * $0.50 / candy = $7 for them. She wants also 20 jellybeans, and they're going to cost 20 jellybeans * $0.20 / jellybean = $4. So after the purchase, she will be left with $22 - $4 - $7 = $11.
The answer: 11
Reverse engineering the question: Sandra wants to buy some sweets. She saved $10 for this purpose. Her mother gave her an additional $4, and her father twice as much as her mother. One candy costs $0.5, and one jelly bean $0.2. She wants to buy 14 candies and 20 jelly beans. How much money will she be left with after the purchase?


Reasoning and answer: Now that he is an adult, Bobby can jump 60 * 1 = 60 jumps per minute. Bobby can jump 60 - 30 = 30 more jumps than when he was a child.
The answer: 30

First find the total numbers of marbles: 14 + 20 + 19 + 7 = 60 marbles. After sharing them equally each person will get 60 marbles / 4 people = 15 marbles / person.
The answer: 15
Reverse engineering the question: Dilan, Martha, Phillip, and Veronica went to the park together to have some fun. They all had a different number of marbles: Dilan had 14 marbles, Martha had 20 marbles, Phillip had 19 marbles and finally, Veronica had only 7 marbles. They wanted to redistribute the marbles so they each had an equal number. How many marbles did each friend have at the end of the day?


Reasoning and answer: April has 30 days, so if he didn't walk the dog on Sundays, he worked for a total of 30 days - 4 days = 26 days. If each day he earned $10, he ends up with 26 days * $10 / day = $260 . After buying books and giving his sister $50, he ends up with $260 - $50 - $50 = $160.
The answer: 160
What was the question?
Question: John's neighbor tells him to walk his dog for 1 hour each day for a total of $10. He does this for April, save for the 4 Sundays in April. He later spent $50 on books and gave his sister Kaylee the same amount. How much money did John have left?


Reasoning and answer: The 3 pigs that are sold after 12 months will cost the farmer 12 * 10 * 3 = $360 in food costs. The 3 pigs that are sold after 16 months will cost the farmer 16 * 10 * 3 = $480 in food costs. Thus, the total food cost to raise the 6 piglets was 360 + 480 = $840. Next, selling the 6 fully grown pigs will earn the farmer 6 * 300 = $1800 in revenue. Therefore, the earn the farmer 1800 - 840 = $960 in profit from these sales.
The answer: 960

A farmer owns a hog that recently gave birth to 6 piglets. If the farmer raises the piglets until they are fully grown, he can sell the fully grown pig for $300. Each piglet must grow for at least 12 months before it is large enough to be sold. It costs the farmer $10 per month to feed each animal until it is sold. If the farmer sells 3 pigs after 12 months, and the remaining 3 pigs after 16 months, how much profit did he earn in total (after deducting the cost of food)?
