Q: A baker sells pastries for $5 and works 7 days a week. On Monday he sold 2. Every day the number of sales increases by 1 compared to the previous day. On average, how many pastries does he sell on each day of the week?
A: You know from the statement that on Monday he sells 2 pastries, so on Tuesday he sells 3, Wednesday 4, Thursday 5, Friday 6, Saturday 7 and Sunday 8 pastries. So the average value is (2 + 3 + 4 + 5 + 6 + 7 + 8) pastries / 7 days. The baker sells, on average, 35 / 7 = 5 pastries / day for 1 week. The answer is 5.

Q: A bag of dozen apples costs $14 and Brian has already spent $10 on kiwis and half that much on bananas. What's the maximum number of apples Brian can buy if he left his house with only $50 and needs to pay the $3.50 subway fare each way?
A: Brian requires a total of $3.50 + $3.50 = $7 to pay for the round trip subway fare. We also know he has spent half (1 / 2) the amount he spent on kiwis on bananas, so he'll spend (1 / 2) * $10 = $5 on bananas. So far in total he has spent $7 for his subway fare + $5 on bananas + $10 on kiwis = $7 + $5 + $10 = $22. If he left his house with only $50, then all he will have left for apples would be $50 - $22 = $28. If a bag of apples costs $14, then Brian would only be able to buy a maximum of $28 / $14 = 2 bags of apples. If each bag of apples has a dozen (12) apples, then (2) two bags will have 12 * 2 = 24 apples. The answer is 24.

Q: Lee is saving up for a new pair of sneakers which cost $90. He already has $15 saved. He plans to sell his old action figures to make the rest. If he sells 10 action figures and still has $25 left after buying the sneakers how much did he charge per action figure?
A:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.

Before buying the shoes he had $115 dollars because 90 + 25 = 115. He earned $100 from selling action figures because 115 - 15 = 100. He sold them each for $10 because 100 / 10 = 10. The answer is 10.
