The cable company charges $30 to install new supplies at your house. Each month the cable bill is $75. Which equation models the total cost for cable over time?

Question

which one of these is it

y = 30x + 75

y = 30x – 75

y = 75x – 30

y = 75x + 30

Answer 1

y = 75x + 30

The 30 dollar installation fee never changes, so it's constant. For every x months, you will be charged 75 dollars.
