Answer:

  380 = 40h +200 (equation)

  4 1/2 hours (solution)

Step-by-step explanation:

The total cost is the sum of labor cost and parts cost. The labor cost depends on the number of hours.

__

An equation describing Terry's charges might be ...

  total = labor cost + parts cost

  380 = 40h +200 . . . . . . labor was $40 per hour for each of h hours

  180 = 40h . . . . . . subtract 200

  4.5 = h . . . . . . divide by 40

Terry was charged for 4 1/2 hours of labor.
