Question

Write a Linear Equation in the form y = mx + b for the following situation: Syd and her friends are washing cars over the summer. Without a membership, each car costs $10 to wash. With a membership, you would pay a $10 flat fee and receive washes for only $4 per car! Which linear equation below reflects the cost per car with a membership? *

Answer 1

y=4x+10

Explanation:

If $10 is a flat fee, then that is your constant; it doesn't change.

If $4 per car, then 4 is your coefficient.

Therefore, your equation is y=4x+10
