US Units of Measurements Walmart sells lemons at $0.68 each. Each lemon yields about 4 tablespoons of juice. How much will it cost to buy enough lemons to make four 9-inch lemon pies, each requires 3/4 of a cup of lemon juice?
The Correct Answer and Explanation is:
To solve this problem, we need to determine how many lemons are needed to produce enough lemon juice for four 9-inch lemon pies, and then calculate the total cost of those lemons.
Step 1: Convert cups of lemon juice to tablespoons
Each pie requires 3/4 cup of lemon juice. Since there are 16 tablespoons in a cup:Lemon juice per pie=34 cup×16 tablespoons/cup=12 tablespoons\text{Lemon juice per pie} = \frac{3}{4} \text{ cup} \times 16 \text{ tablespoons/cup} = 12 \text{ tablespoons}Lemon juice per pie=43 cup×16 tablespoons/cup=12 tablespoons
For four pies:Total lemon juice for four pies=4×12 tablespoons=48 tablespoons\text{Total lemon juice for four pies} = 4 \times 12 \text{ tablespoons} = 48 \text{ tablespoons}Total lemon juice for four pies=4×12 tablespoons=48 tablespoons
Step 2: Calculate how many lemons are needed
Each lemon yields 4 tablespoons of juice. To find out how many lemons are needed for 48 tablespoons of juice:Number of lemons=48 tablespoons4 tablespoons per lemon=12 lemons\text{Number of lemons} = \frac{48 \text{ tablespoons}}{4 \text{ tablespoons per lemon}} = 12 \text{ lemons}Number of lemons=4 tablespoons per lemon48 tablespoons=12 lemons
Step 3: Calculate the cost of the lemons
Since each lemon costs $0.68:Total cost of lemons=12 lemons×0.68 dollars per lemon=8.16 dollars\text{Total cost of lemons} = 12 \text{ lemons} \times 0.68 \text{ dollars per lemon} = 8.16 \text{ dollars}Total cost of lemons=12 lemons×0.68 dollars per lemon=8.16 dollars
Conclusion
To make enough lemon juice for four 9-inch pies, it will cost $8.16 for the lemons.
