Answer: The correct option is (C)
Step-by-step explanation: Given that Umesh’s total charge for an onsite job is: a fixed charge of $50 per job, plus an hourly charge of $80 per hour.
We are to select the formula that shows how Umesh’s total charge in dollars, C, relates to the number of hours, h, he spends on a job.
Since the number of hours is h and there is an hourly charge of $80 per hour, so the total charge in h hours will be
50 × h = 50h.
Also, there is a fixed charge of $50 per job, so the total charge of Umesh in dollars will be
Thus, required formula is
Option (C) is CORRECT.
