Question

A computer tech charges a $30 initial fee to come and fix a household computer plus $15 per hour. Which of the following linear equations does this follow?

Answer 1

Answer:

I don't see the choices, but the answer will be  y = 15x + 30, or maybe

c = 15h + 30    with c being the cost, and h being the amount of hours.

Step-by-step explanation:

$30 is a flat rate charged just for showing up, so that value is constant and will not change.  

$15 is the per hour charge, so the total charge will be $30 plus $15 for every hour the tech is there.  The $15 is a constant charge per hour, so let x or h represent the number of hours the tech is there, so the total cost is

c = 15h + 30

Every time h increases by 1, the total cost goes up by $15.
