Question

The store is selling lemons at $0.79 each. Each lemon yields about 2 tablespoons of juice. How much will it cost to buy enough lemons to make three 9-inch lemon pies, each requiring half a cup of lemon juice?

Answer 1

Since each pie requires 1/2 cup of lemon juice and there are 3 pies, you would need 1 and 1/2 total cups of juice. Also, recall that 1 cup is equivalent to 16 tablespoons.

Then 1 and 1/2 cups would be equivalent to 24 tablespoons (1.5 x 16).

Since each lemon provides 2 tablespoons of juice, you would need 12 lemons to get 24 tablespoons.

The cost of 12 lemons would be 12 times $ 0.79 or $9.48

Answer 2

8 tablespoons = 1/2 cup

For three pies, we would need 24 tablespoons of lemon juice (8 tablespoons x 3 pies).

Each lemon produces 2 tablespoons; thus, we would need 12 lemons (24 tablespoons / 2 tablespoons).

To determine the cost, you would multiply the number of lemons by their price:

$0.79 x 12 lemons = $9.48
