Question: A park has 50 benches with a capacity of 4 people each. On a Sunday afternoon, 80 people were sitting on the benches. What's the number of available spaces on the benches that other people can sit on before the carrying capacity of the benches is full?
Answer: In the park, 50 benches with a capacity of four people each have a total capacity of 50 * 4 = 200 sitting spaces. If 80 people are already using spaces, the number of empty spaces is 200 - 80 = 120. The answer is 120.
[Question]Hilary is shucking corn from ears that grew on her farm. She gets four ears of corn per stalk, and she has 108 stalks growing. Half the ears of corn have 500 kernels of corn and the other half have 100 more. How many kernels of corn does Hilary have to shuck?
[Answer]She has 108 * 4 = 432 ears of corn to shuck. She gets 500 kernels of corn from half the ears and 500 + 100 = 600 kernels from the other half. Half the number of ears of corn is 432 / 2 = 216 ears. Thus, Hilary has 216 * 500 + 216 * 600 = 108000 + 129600 = 237600 kernels to shuck. The answer is 237600.

Question: Stan can type 50 words per minute. He needs to write a 5-page paper. Each page will contain 400 words. Each hour that he types he needs to drink 15 ounces of water. How much water does he need to drink while writing his paper?
Answer: Stan needs to write 2,000 words because 5 x 400 = 2,000. This will take him 40 minutes because 2,000 / 50 = 40. He drinks 1 / 4 an ounce per minute because 15 / 60 = 1 / 4. He will drink 10 ounces of water while writing the paper because 40 x (1 / 4) = 10. The answer is 10.
[Question]Three years from now, Tully will be twice as old as Kate. How old was Tully a year ago if Kate is now 29 years old?
[Answer]Three years from now, Kate will be 29 years + 3 years = 32 years old. So by that time, Tully will be 32 years x 2 = 64 years old. This means, Tully is 64 years - 3 years = 61 years old now. Therefore, Tully was 61 years - 1 year = 60 years old last year. The answer is 60.
