Answer this question:Kendall is counting her change. She has a total of $4 in quarters, dimes, and nickels. If she has 10 quarters and 12 dimes, how many nickels does she have?
The total money from the quarters is 10 * $0.25 = $2.50. The total money from the dimes is 12 * $0.10 = $1.20. The total money from the nickels is $4 - $2.50 - $1.20 = $0.30. The number of nickels Kendall has is $0.30 / $0.05 = 6 nickels.
The answer is 6.

Answer this question:The water pressure of a sink has a steady flow of 2 cups per 10 minutes for the first 30 minutes. It still flows at 2 cups per 10 minutes for the next 30 minutes after. For the next hour, the water pressure maximizes to 4 cups per 10 minutes and stops. Shawn now has to dump half of the water away. How much water is left?
For the first 30 minutes, 3 * 2 = 6 cups of water came out. For the next 30 minutes, 3 * 2 = 6 cups of water came out. For the next hour, 6 * 4 = 24 cups of water came out. A total of 6 + 6 + 24 = 36 cups of water came out. Shawn had to dump water which left 36 / 2 = 18 cups of water.
The answer is 18.
