Answer the following question.
Du Chin bakes 200 meat pies in a day. He sells them for $20 each and uses 3/5 of the sales to buy ingredients to make meat pies for sale on the next day. How much money does Du Chin remain with after setting aside the money for buying ingredients?
Step-by-step reasoning process: From the 200 meat pies, Du Chin makes 200 * $20 = $4000 after the sales. The amount of money he uses to buy ingredients to make pies for sale on the next day is 3 / 5 * $4000 = $2400. After setting aside money for buying ingredients, Du Chin remains with $4000 - $2400 = $1600.
The answer is 1600.

Answer the following question.
A hand-crank pencil sharpener can sharpen one pencil every forty-five seconds. An electric version can sharpen one in twenty seconds. How many more pencils can the electric sharpener sharpen than the hand-crank sharpener in six minutes?
Step-by-step reasoning process: A minute is 60 seconds, so 6 minutes is 6 * 60 = 360 seconds. A hand - crank sharpener can sharpen 360 / 45 = 8 pencils in 6 minutes. An electric sharpener can sharpen 360 / 20 = 18 pencils in 6 minutes. Therefore, an electric sharpener can sharpen 18 - 8 = 10 more pencils than a hand - crank in 6 minutes.
The answer is 10.

Answer the following question.
Rebecca bought 2 pies for the holiday weekend. Each pie was sliced into 8 slices. Rebecca ate 1 slice of each pie. Her family and friends ate 50% of the remaining pies over the weekend. On Sunday evening Rebecca and her husband each had another slice of pie. How many slices are remaining?
Step-by-step reasoning process: She bought 2 pies that had 8 slices each for a total of 2 * 8 = 16 slices. Rebecca ate 2 of the 16 slices leaving 16 - 2 = 14 slices. Her family and friends at 50% of the pie so they ate 14 * .50 = 7 slices. There were 14 slices and her family and friends ate 7 slices so that leaves 14 - 7 = 7 slices. Sunday night Rebecca and her husband each had a slice from the remaining slices so that leaves 7 - 2 = 5 slices.
The answer is 5.

Answer the following question.
Peyton Manning throws a football 20 yards when the temperature is 50 degrees Fahrenheit, but the ball moves twice as far when the temperature is 80 degrees Fahrenheit. Last Saturday, the temperature was 50 degrees Fahrenheit, and he threw the ball twenty times. On Sunday, the temperature rose to 80 degrees Fahrenheit, and he threw the ball 30 times. Calculate the total number of yards he threw the ball in the two days.
Step-by-step reasoning process: On Saturday, he threw the ball 20 times, and since the temperature was 50 degrees, he could throw only 20 yards, totaling 20 * 20 = 400 yards. On Sunday, the temperature favored him, and he threw the ball twice the distance he could throw on Saturday, which is 2 * 20 = 40 yards. If he threw the ball 30 times, he threw for 30 * 40 = 1200 yards. In the two days, he threw 1200 + 400 = 1600 yards.
The answer is 1600.
