[Question]Theodore can craft 10 stone statues and 20 wooden statues every month. A stone statue costs $20 and a wooden statue costs $5. He also pays 10 percent of his total earnings in taxes. How much is his total earning every month?
[Answer]Theodore's total earnings from the stone statues are 10 x $20 = $200. His total earnings from wooden statues are 20 x $5 = $100. So his total earnings from the stone and wooden statue are $200 + $100 = $300. The amount he pays for the tax is $300 x 10 / 100 = $30. Therefore his total monthly earnings are $300 - $30 = $270. The answer is 270.
Q: Basil gets 1/2 of a dog cookie in the morning and before bed. She gets 2 whole cookies during the day. Basil’s cookies are packaged with 45 cookies per box. How many boxes will she need to last her for 30 days?
A: Basil gets 1 / 2 in the morning and 1 / 2 at bedtime so she gets 1 / 2 + 1 / 2 = 1 whole cookie. Basil also gets 2 whole cookies during the day so all total she gets 2 + 1 = 3 whole cookies. She needs cookies for 30 days and eats 3 a day so she needs 30 * 3 = 90 cookies. Her cookies come 45 per box and she needs 90 cookies so she needs 90 / 45 = 2 boxes of cookies. The answer is 2.
Question: Chang's Garden has two kinds of apples. Sweet ones and sour ones. He can sell the sweet ones for $.5 an apple. The sour ones sell for $.1 an apple. 75% of the apples he gets are sweet and the rest are sour. If he earns $40, how many apples did his trees give him?
Answer: 25% of the apples are sour because 100 - 75 = 25. The average price of an apple sold is $.4 because .75(.5) + .25(.1) = .4. He got 100 apples because 40 / .4 = 100. The answer is 100.

[Question]Ann's favorite store was having a summer clearance. For $75 she bought 5 pairs of shorts for $7 each and 2 pairs of shoes for $10 each. She also bought 4 tops, all at the same price. How much did each top cost?
[Answer]
She bought 5 shorts at $7 each so 5 * 7 = $35. She bought 2 pair of shoes at $10 each so 2 * 10 = $20. The shorts and shoes cost her 35 + 20 = $55. We know she spent 75 total and the shorts and shoes cost $55 which left a difference of 75 - 55 = $20. She bought 4 tops for a total of $20 so 20 / 4 = $5. The answer is 5.
