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.
