Question: 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. If he recycled 80 bottles and made $15, how many cans did he recycle?
Answer: Step-by-step reasoning process: First find the total amount Jack earned from the bottles: $0.10 / bottle * 80 bottles = $8.00. Then subtract that amount from his total earnings to find the amount he earned from cans: $15.00 - $8.00 = $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 = 140 cans.
So the answer is 140.

Question: Levi and his brother were playing basketball. Levi had scored 8 times and his brother had scored 12 times. Levi was determined to beat his brother by at least 5 baskets. How many more times does Levi have to score in order to reach his goal if his brother scores another 3 times?
Answer: Step-by-step reasoning process: Altogether, Levi's brother scores 12 + 3 = 15 times. If Levi wants to beat him by 5, he needs to score a total of 15 + 5 = 20 times. Levi needs to score another 20 - 8 = 12 times.
So the answer is 12.

Question: James builds a 20 story building. The first 10 stories are each 12 feet tall each. The remaining floors are each 3 feet taller. How tall is the building?
Answer: Step-by-step reasoning process: The first 10 floors are 10 * 12 = 120 feet. There are a remaining 20 - 10 = 10 stories. They are each 12 + 3 = 15 feet. So those stories are 15 * 10 = 150 feet. So the total height is 120 + 150 = 270 feet.
So the answer is 270.

Question: If Buzz bought a pizza with 78 slices at a restaurant and then decided to share it with the waiter in the ratio of 5:8, with Buzz's ratio being 5, what's twenty less the number of slices of pizza that the waiter ate?
Answer:
Step-by-step reasoning process: The total ratio representing the slices of pizza that Buzz bought is 5 + 8 = 13. If he shared the slices of pizza with the waiter, the waiter received a fraction of 8 / 13 of the total number of slices, which totals 8 / 13 * 78 = 48 slices. Twenty less the number of slices of pizza that the waiter ate is 48 - 20 = 28.
So the answer is 28.
