Question

just before her party starts, jane fills a cooler with 80 cups of ice. she also starts filling glasses with ice, 0.8 cups each. write an equation that shows how the total number of cups of ice used, y, depends on the number of glasses filled, x. y =

Explanation:

Step1: Identify fixed ice amount

Jane uses 80 cups of ice for the cooler, which is a constant value.

Step2: Calculate ice for glasses

Each glass uses 0.8 cups, so for $x$ glasses, ice used is $0.8x$.

Step3: Total ice used equation

Add fixed and variable ice amounts to get total $y$.
$y = 80 + 0.8x$

Answer:

$y = 0.8x + 80$
