Question: Ned opens a left-handed store. He sells left-handed mice. They cost 30% more than normal mice. He sells 25 a day and his store is open every day except Sunday, Thursday, and Friday. If normal mice cost $120 how much money does he make a week?
Answer: Step-by-step reasoning process: The left - hand mice cost 120 * .3 = $36 more than right - handed ones. So they cost 120 + 36 = $156. So he makes 156 * 25 = $3900 a day. The store is open 7 - 3 = 4 days a week. So in a week, he makes 3900 * 4 = $15,600.
So the answer is 15600.

Question: At peak hours, 11 am - 1 pm and 5 pm - 6 pm, the local fast-food restaurant serves 12 cars every 15 minutes. Off-peak times, they serve 8 cars every 15 minutes. From 4 pm - 6 pm, how many customers do they serve?
Answer:
Step-by-step reasoning process: 5 pm - 6 pm is one hour and they measure service in 15 - minute blocks so 60 / 15 = 4 15 min blocks. At peak times, they serve 12 cars every 15 minutes so they serve 12 * 4 = 48 cars in 60 minutes. Off peak times, 4pm - 5 pm, they serve 8 cars every 15 minutes so they serve 8 * 4 = 32 cars in 60 minutes. From 4pm - 5 pm they serve 32 cars and from 5pm - 6 pm they serve 48 cars so they serve 32 + 48 = 80 cars.
So the answer is 80.
