Question 7: The store sells lemons for $0.43 each. Each lemon yields approximately 2 tablespoons of juice. How much will it cost to purchase enough lemons to make four 9-inch lemon pies if each pie requires a half cup of lemon juice?

 To calculate the cost of the lemons needed to make four 9-inch lemon pies, we need to figure out how many lemons are needed to yield the required amount of lemon juice.

First, let's determine the amount of lemon juice needed for four pies. - One pie requires half a cup of lemon juice. - Therefore, four pies would require 4 x (1/2 cup) = 2 cups of lemon juice.

Now, let's convert cups to tablespoons to match the yield per lemon: - One cup equals 16 tablespoons. - Therefore, 2 cups equal 32 tablespoons (since 2 x 16 = 32).

If each lemon yields 2 tablespoons of juice, let's find out how many lemons this would equate to: - We have 32 tablespoons of juice needed. - Each lemon gives us 2 tablespoons. - Hence, we would need 32 / 2 = 16 lemons.

Now that we know we need 16 lemons, we can calculate the cost: - Each lemon costs $0.43. - So, the total cost for 16 lemons would be 16 x $0.43 = $6.88.

Therefore, it will cost $6.88 to purchase enough lemons to make four 9-inch lemon pies.
