Consider the Q and A. Q: Caprice is taking piano lessons. Her mother pays the teacher $10 for every half-hour of teaching her daughter. If Caprice is taking one lesson per week, and the lesson lasts 1 hour, how much money would the teacher earn in 5 weeks?
A: 100
What is the step-by-step reasoning process?
Step-by-step reasoning process: If half - hour lesson is worth $10, then a one - hour lesson costs 2 * 10 = $20. One lesson per week would mean that in 5 weeks the teacher would earn 20 * 5 = $100.

Consider the Q and A. Q: Amy bought a 15-foot spool of string to cut up into wicks for making candles.  If she cuts up the entire string into an equal number of 6-inch and 12-inch wicks, what is the total number of wicks she will have cut?
A: 20
What is the step-by-step reasoning process?
Step-by-step reasoning process: 15 feet of string is 15 * 12 = 180 inches long. If for every 6 - inch wick she also cuts a 12 - inch wick, then the pair of wicks are 6 + 12 = 18 inches long. Thus, in 180 inches of string, she can cut 180 / 18 = 10 pairs of wicks. 10 pairs of wicks are a total of 10 * 2 = 20 wicks.

Consider the Q and A. Q: Tim drops a ball off the roof of a 96-foot tall building. The ball bounces to half the height from which it fell on each bounce. How high will it bounce on the fifth bounce?
A: 3
What is the step-by-step reasoning process?
Step-by-step reasoning process: On the first bounce, it will reach a height of 96 / 2 = 48 feet. On the second bounce, it will reach a height of 48 / 2 = 24 feet. On the third bounce, it will reach a height of 24 / 2 = 12 feet. On the fourth bounce, it will reach a height of 12 / 2 = 6 feet. On the fifth bounce, it will reach a height of 6 / 2 = 3 feet.

Consider the Q and A. Q: Mr. Callen bought 10 paintings at $40 each and 8 wooden toys at $20 each from the crafts store to resell at a profit. However, when he sold the items, the selling price of a painting was 10% less and the selling price of a hat 15% less. Calculate the total loss Mr. Callen made from the sale of the items.
A: 64
What is the step-by-step reasoning process?
Step-by-step reasoning process:
If he sold a painting at a 10% loss, then he made a 10 / 100 * $40 = $4 loss on each painting. since he bought 10 paintings, the total loss he made from selling the paintings is 10 * $4 = $40. He also made a loss of 15 / 100 * 20 = $3 loss from selling each wooden toy. Since he bought 8 wooden toys, the total loss he made was 3 * 8 = $24. In total, Mr. Callen made a loss of $40 + $24 = $64 from the sales of the items.
