Question

One electrician charges a flat fee of $55 to come to the house, $20 per

hour, and the cost of all materials. If h represents the number of hours that
the electrician spent fixing the problem, C represents the total charge, and m
represents the cost of materials, which of the following equations shows how
to determine the total fee charged?

C=20+55h+m

C=mh+55 +20

C=(55+20)h+m

C=55+20h+m

Answer 1

C=55+20h+m

Explanation:

C = flat fee + dollars/hour + material expense

C = 55 + 20h + m

Hope this helps
