Q: Olivia gave William 10 napkins. Amelia also gives William twice the number of napkins Olivia gave him. If William had 15 napkins before, how many napkins does he have now?

[Question]Mrs. Oaklyn buys handmade rugs at $40 each and sells them at $60 each. If she bought 20 rugs, calculate the profit she will make from selling the rugs.
[Answer]Since she buys one rug at $40 and sells it at $60, she makes a profit of $60 - $40 = $20. If she bought 20 rugs at $40 and sold them at $60 each, she made a profit of 20 * $20 = $400. The answer is 400.

Q: 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?
A:
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. The answer is 80.
