Answer:
It will cost $6 to buy enough lemons.
Step-by-step explanation:
Consider the provided information.
To make a 9-inch lemon pie requiring 1/2 cup of lemon juice.
1 cup = 16 tablespoons
1/2 cup = 8 tablespoons
That means we only need 8 tablespoons.
Each lemon yields 2 tablespoons of lemon juice.
Number of lemon required = 8 ÷ 2 = 4
That means we need only 4 lemon.
Store is selling lemons at 2 for $3 that means 4 lemons for $6.
Hence, it will cost $6 to buy enough lemons.
First take note of her total amount of money, the amount of magazine cost, and the total weeks they purchased it.
Total: $88
Cost: $3.75
Weeks: 5
Now setup and equation.
88-(3.75 x 5)
88-18.75=69.25
So she will have $69.25 after the 5 weeks of purchasing magazines
