Q: Jenny lives 5000 feet from her school, and every day she walks home. One day as she was walking home from school, she dropped 1 kernel of popcorn per 25 feet she walked. Later that evening, a squirrel came and ate one-quarter of the popcorn Jenny had dropped on her way home. If Jenny walks to school the following morning and counts the popcorn on the ground, what is the total number of popcorn kernels she will find remaining on the ground?
A: She originally dropped 5000 / 25 = 200 kernels of popcorn. The squirrel ate 200 / 4 = 50 kernels of popcorn. Therefore, 200 - 50 = 150 kernels of popcorn remain on the ground. The answer is 150.

Q: Jerry is refilling the duck pond in his backyard during a drought. The pond can hold 200 gallons of water. Jerry's hose can normally pump 6 gallons/minute, but due to drought restrictions, it can only pump 2/3rds as fast right now. How many minutes will it take Jerry to fill his pond?
A: First find the current rate the hose pumps by multiplying its normal rate by 2 / 3: 6 gallons / minute * 2 / 3 = 4 gallons / minute. Then divide the number of gallons in the pond by the number of gallons pumped each minute to find how many minutes filling the pond takes: 200 gallons / 4 gallons / minute = 50 minutes. The answer is 50.

Q: Bart buys $10 of notepads for $1.25 each. They have 60 pages each. How many pages did he buy?
