Question

Christina is a salesperson. Let y represent her total pay (in dollars). Let x represent the number of items she sells. Suppose that x and y are related by the equation y equals 36 x plus 4500.

What is Christina’s total pay if she doesn’t sell any items?

Answer 1

$4500

Explanation:

1. Set x to 0 because she sells 0 items, so that you have y=36(0)+4500

2. y=4500 because 36x0=0, so only 4500 is left on the right side of the equation

3. Y is her total pay, so Christina receive s $4500.
