Question

Joey's cleaning service charges $50 per week to clean a home. Amy's cleaning service charges $50 per week , plus $25 for cleaning supplies.

which equation can be used to express the amount that Amy's cleaning service charges?

A y=50x

B y=50x-25

C y=1/50x

D y=50x + 25

Answer 1

D

Explanation:

y = mx + b is the equation, where m = cost per week and b = cleaning supply cost (constant)

That means the equation is y = 50x + 25

Answer 2

D y=50x + 25

Explanation:

The number of weeks can vary, so it is placed in front of a variable. The cleaning supplies cost does not, so it does not have a variable, but instead, it is a constant.
