Q: Levi and his brother were playing basketball. Levi had scored 8 times and his brother had scored 12 times. Levi was determined to beat his brother by at least 5 baskets. How many more times does Levi have to score in order to reach his goal if his brother scores another 3 times?
A: Altogether, Levi's brother scores 12 + 3 = 15 times. If Levi wants to beat him by 5, he needs to score a total of 15 + 5 = 20 times. Levi needs to score another 20 - 8 = 12 times. The answer is 12.
Question: James buys 20 coins of a cryptocurrency at $15 each. The value of the coins increases by 2/3. He sells coins to recoup his original investment. How many coins did he sell?
Answer: His original investment was 15 * 20 = $300. The value of his investment increases by 15 * 2 / 3 = $10 per coin. So each coin was worth 15 + 10 = $25. So he sold 300 / 25 = 12 coins. The answer is 12.
[Question]A trader made a profit of $960 after a week of sales. To raise $610 to pay for her next shipment of wares, she splits the profit in half and solicits donations from her family and friends. If she received a total donation of $310 and adds it to one-half of her profit, how much money did she make above her goal?
[Answer]She splits her $960 profit in half to get $960 / 2 = $480. She receives a total donation of $310, so she now has $310 + $480 = $790. She needed only $610 so she has $790 - $610 = $180 more than she needs. The answer is 180.

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:
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.
