How much will it cost to buy enough lemons to make four 9-inch lemon pies, each requiring half a cup of lemon juice?

Question

The store is selling lemons at $0.37 each. Each lemon yields about 2 tablespoons of juice. How much will it cost to buy enough lemons to make four 9-inch lemon pies, each requiring half a cup of lemon juice?

Answer 1

16 tbsp = 1 cup

8 tbsp = 1/2 cup

therefore each pie requires 8 tbsp of juice

and each pie requires 4 lemons (4 lemons * 2 tbsp juice per lemon)

4 pies will require 16 lemons @ $0.37

You should be able to figure the total cost from here.
