Q: Apollo pulls the sun across the sky every night. Once a month, his fiery chariot’s wheels need to be replaced. He trades golden apples to Hephaestus the blacksmith to get Hephaestus to make him new wheels. Hephaestus raised his rates halfway through the year and now demands twice as many golden apples as before. He charged three golden apples for the first six months. How many golden apples does Apollo have to pay for the entire year of chariot wheels?
A: Apollo had to pay 3 * 6 = 18 golden apples for the first six months. For the second six months, he had to pay twice that amount, or 18 * 2 = 36 golden apples. Thus, Apollo had to pay 18 + 36 = 54 golden apples for a year of chariot wheels. The answer is 54.

Q: Autumn was constantly misplacing her pencils. At the start of the school year, she purchased a pack of 20 pencils. In the first month of school, she misplaced 7 pencils, broke 3 pencils and had to throw them away, she found 4, and bought 2. How many pencils did Autumn have left?
A: Autumn misplaced 7 and broke 3, so that lost her 7 + 3 = 10 pencils. Autumn found 4 pencils and bought 2, so she gained 4 + 2 = 6 pencils. She started with 20 pencils, lost 10 and gained 6 so she had 20 - 10 + 6 = 16 pencils left. The answer is 16.

John's pants cost 50 * .6 = $30 more than his pants. So his shirt cost 50 + 30 = $80. So in total he spent 80 + 50 = $130. The answer is 130.
