Question

isaac works at a deli. he made a 30 - cup batch of potato salad, and now he is filling 2.5 - cup to - go containers to sell to customers. write an equation that shows how the number of cups of potato salad remaining, y, depends on the number of to - go containers isaac has filled, x.

Explanation:

Step1: Identify the initial amount

The initial amount of potato - salad is 30 cups.

Step2: Identify the amount used per container

Each to - go container uses 2.5 cups. So for x containers, the total amount used is 2.5x cups.

Step3: Find the remaining amount

The remaining amount y of potato - salad is the initial amount minus the amount used for x containers. So the equation is $y = 30−2.5x$.

Answer:

$y = 30 - 2.5x$
