A repair shop charges $50 per hour. This week it is offeringa $20 discount. The equation c = 50h - 20 represents thetotal cost, c, of a job taking h hours. What is the total costof a job that takes 6 hours?

Answer 1

The cost to repair is based on hours of work ($50 per hour)

nd the total cost for repair this week is reduced by $20 according to the offer.

Using the formula: C = 50 h - 20

we can find the total cost of a repair that takes 6 hours by doing:

C = 50 (6) -20 = 300 - 20 = 280

So the repair job will cost $280
