[Question]Bruce buys 5 packs of crayons at $5 each, 10 books at $5 each, and 3 calculators at $5 each. If he has $200, how many bags can he buy with the change if one costs $10 each?
[Answer]He pays 5 * 5 = $25 for buying crayons. He pays 10 * 5 = $50 for buying books. He pays 3 * 5 = $15 for buying calculators. The change he has for buying bags is 200 - 25 - 50 - 15 = $110. The number of bags he can buy is 110 / 10 = 11 bags. The answer is 11.
Q: A family's water and electricity bills average $30 a month for the first 4 months and $24 a month for the last 2 months. If the family's bills were averaged over all 6 months, what would the average monthly bill be?
A: The sum of the bills of the family in the first 4 months is $30 / month x 4 months = $120. The sum of the bills of the family in the last 2 months is $24 / month x $2 = $48. The sum of the bills of the family over the 6 months is $120 + $48 = $168. Hence, their average monthly bill is $168 / 6 months = $28 / month. The answer is 28.
Question: Ben bought a lawnmower for his garden. He paid $100 for it. After six months, the value of the mower dropped by about 25%. Over the next year, the value of the mower dropped another 20% in value. How much is Ben's lawnmower worth after this time?
Answer: The first value drop of the lawnmower was 25 / 100 * 100 = $25. So the lawnmower was worth 100 - 25 = $75. Over the next year, the value dropped another 20%, which is 20 / 100 * 75 = $15. So after all this time, Ben's lawnmower is worth 75 - 15 = $60. The answer is 60.
