Q: Tommy is making 12 loaves of bread. He needs 4 pounds of flour per loaf. A 10-pound bag of flour costs $10 and a 12-pound bag costs $13. When he is done making his bread, he has no use for flour and so he will throw away whatever is left. How much does he spend on flour if he buys the cheapest flour to get enough?
A: He needs 48 pounds of flour because 12 x 4 = 48. He needs 4.8 bags of 10 pound bags because 48 / 10 = 4.8. He therefore needs to buy 5 bags of flour because 4 < 4.8 < 5. He spends $50 if he buys this flour because 5 x 10 = 50. He needs 4 bags of the 12 - pound flour because 48 / 12 = 4. He would spend $52 on the 12 - pound bags because 4 x 13 = 52. He spends $50 if he buys the cheapest flour because 50 < 52. The answer is 50.
Question: At Snowflake Plastics, each employee gets 10 sick days and 10 vacation days per year. If Mark uses half his allotment of both types of days in a year, how many hours' worth of days does he have left if each day covers an 8-hour long workday?
Answer: First, we add the two types of days together to find 10 + 10 = 20 days in total between the two types. We then divide this number in half to find Mark's remaining number of days, getting 20 / 2 = 10 days remaining. Since each day counts as 8 hours, we multiply 10 * 8 = 80 hours' worth of days remaining for Mark. The answer is 80.

Q: James decides to buy a living room set. The coach cost $2500 and the sectional cost $3500 and everything else has a combined cost of $2000. He gets a 10% discount on everything. How much did he pay?
