Question

At the salad bar, the grocery store charges $5.99 for each half pound you buy. Which variable is dependent?

Thank you! <3

Answer 1

See below.

Explanation:

cost = function of the number of half pounds you buy

Let n = number of half pounds you buy.

Let c = cost.

The cost function is

c = 5.99n

n is the independent variable. The number of half pounds you buy is any number you choose. Once you have a fixed number for n, then c depends on that number.

c is the dependent variable.
