Question: Catherine had an equal number of pencils and pens. If she had 60 pens and gave eight pens and 6 pencils to each of her seven friends and kept the rest for herself, how many pens and pencils did she have left?
Answer: Step-by-step reasoning process: Catherine gave eight pens to each of her seven friends, a total of 8 * 7 = 56 pens. She remained with 60 - 56 = 4 pens. When she also gave 6 pencils to each of her seven friends, she gave away 6 * 7 = 42 pencils. Since she had the same number of pencils as pens, she remained with 60 - 42 = 18 pencils. The total number of pens and pencils that Catherine remained with is 4 + 18 = 22.
So the answer is 22.

Question: When it rains, the three holes in the garage roof leak water at different rates. The largest hole leaks at a rate of 3 ounces of water per minute. The medium-sized hole leaks water at one-half the rate of the largest hole. And the smallest hole leaks water at a rate of one-third the rate of the medium-sized hole. When it rains, what is the combined amount of water, in ounces, that leak from all three holes over a 2-hour time period?
Answer:
Step-by-step reasoning process: The medium - sized hole leaks at a rate of one - half that of the largest hole, or 3 / 2 = 1.5 ounces per minute. The small - sized hole leaks at a rate of one - third that of the medium - sized hole, or 1.5 / 3 = 0.5 ounces per minute. Combined, the three holes leak at a rate of 3 + 1.5 + 0.5 = 5 ounces per minute. Since one hour is 60 minutes, two hours is 2 * 60 = 120 minutes. In total, over the two hours, the three holes will leak a combined 120 * 5 = 600 ounces of water.
So the answer is 600.
