[Question]: A pie shop charges $3 per slice of custard pie. They cut each whole pie into 10 slices. If they make 6 whole custard pies, how much money will the pie shop earn?
[Answer]: The pie shop has 6 x 10 = 60 slices of custard pie. Therefore, the pie shop will earn $3 x 60 = $180 for the 60 slices of custard pie.
So the answer is 180.

[Question]: Carmen needs $7 more to have twice the amount of money that Jethro has. Meanwhile, Patricia has $60, which is 3 times as much as Jethro. What is the sum of all their money?
[Answer]: Jethro has 60 / 3 = $20. Twice of what Jethro has is $20 x 2 = $40. Carmen has $40 - 7 = $33. The sum of all their money is $60 + $20 + $33 = $113.
So the answer is 113.

[Question]: The house is 20.5 feet by 10 feet. The porch measures 6 feet by 4.5 feet. The house and the porch need shingles. How many square feet of shingles will be needed to roof the house and the porch?
[Answer]:
House = 20.5 * 10 = 205 square feet. Porch = 6 * 4.5 = 27 square feet. 205 + 27 = 232 square feet. 232 square feet of shingles will be needed.
So the answer is 232.
