The store is selling lemons at $0.58 each. Each lemon yields about 2 tablespoons of juice. How much will it cost to buy enough l

avanturin [10]

Answer:

$4.64

Step-by-step explanation:

1 cup = 16 tablespoons

$\frac{1}{2}$ cup = 8 tablespoons

Each lemon yields about 2 tablespoons of juice. You need 8 tablespoons for one lemon pie, so you need $8\div 2=4$ lemons for one pie and $4\times 2=8$ lemons for two pies.

The store is selling lemons at $0.58 each, hence, 8 lemons will cost

$\$0.58\times 8=\$4.64$
