Question: Bob grew corn in his garden this year and ended up with 50 bushels. This is way too much for him to eat, so he gave some of it away to his friends. His friend Terry took 8 bushels, while Jerry only took 3. He gave 12 bushels to his friend Linda, who runs a food pantry. His neighbor Stacy doesn't eat much corn, but she still accepted 21 ears of corn from him. If each bushel contained 14 ears of corn, how many ears of corn does Bob have left?
Answer: Stacy took 21 ears of corn, there are 14 ears to a bushel, so she took 21 ears / 14 ears / bushel = 1.5 bushels of corn. In all, Bob gave away 8 bushels + 3 bushels + 12 bushels + 1.5 bushels = 24.5 bushels of corn. This leaves him with 50 bushels - 24.5 bushels = 25.5 bushels of corn. At 14 ears of corn per bushel, Bob has 25.5 bushels * 14 ears per bushel = 357 ears of corn. The answer is 357.

For every multicolored duck there are 12 fish and there are 6 multicolored ducks for a total of 12 * 6 = 72 fish. All total there are 15 + 70 + 72 = 157 fish in the lake. The answer is 157.
Question: In Canada, for every moose there are two beavers, and for every beaver there are 19 humans. If there are 38 million people in Canada, what is the moose population of Canada, in millions?
Answer: If there are 19 humans for every one beaver, then there are 38 million / 19 = 2 million beavers in Canada. And if for every one moose there are two beavers, then the moose population of Canada is 2 million / 2 = 1 million. The answer is 1.
Q: Tony puts $1,000 in a savings account for 1 year. It earns 20% interest. He then takes out half the money to buy a new TV. The next year, the remaining money earns 15% interest. How much is now in the account?
A:
After one year he earns $200 in interest because 1,000 x .2 = 200. After one year it has $1,200 in the account because 1,000 + 200 = 1,200. He takes out $600 because 1,200 / 2 = 600. After this it has $600 in it because 1,200 - 600 = 600. She earns $90 in interest because 600 x .15 = 90. The account now has $690 because 600 + 90 = 690. The answer is 690.
