Umesh’s total charge for an onsite job is: a fixed charge of $50 per job, plus an hourly charge of $80 per hour. Which one of the following formulas shows how Umesh’s total charge in dollars, C, relates to the number of hours, h, he spends on a job?
= 50h – 80

C = 50h + 80

C = 80h – 50

C = 80h + 50

C = 130h

It's C = 80h + 50. Umesh gets 80$ per hour(80 * h), plus 50 per job, no matter how much time he spends on it. 

Answer:  The correct option is (C) [tex]C=80h+50.[/tex]

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

[tex]C=80h+50.[/tex]

Thus, required formula is [tex]C=80h+50.[/tex]

Option (C) is CORRECT.
