Q: Lydia has a small pool she uses to bathe her dogs. When full, the pool holds 60 gallons of water. She fills her pool using the garden hose, which provides water at the rate of 1.6 gallons per minute. Unfortunately, her pool has a small hole that leaks water at a rate of 0.1 gallons per minute. How long will it take for her to fill the pool, in minutes?
A: With a garden hose that fills at a rate of 1.6 gallons per minute, and a hole that leaks at 0.1 gallons per minute, the net fill rate becomes 1.6 - 0.1 = 1.5 gallons per minute. Therefore, to fill a 60 - gallon pool, it will take 60 / 1.5 = 40 minutes. The answer is 40.
Question: 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.
Answer: 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. The answer is 64.

Q: Of the 90 people on William's bus, 3/5 were Dutch. Of the 1/2 of the Dutch who were also American, 1/3 got window seats. What's the number of Dutch Americans who sat at the windows?
A: On the bus, the number of Dutch people was 3 / 5 of the total number, a total of 3 / 5 * 90 = 54 people. Out of the 54 people who were Dutch, 1 / 2 were Dutch Americans, a total of 1 / 2 * 54 = 27 people. If 1 / 3 of the passengers on the bus identifying as Dutch Americans sat at the windows, their number is 1 / 3 * 27 = 9. The answer is 9.
