Acable company uses the function f(h) = 30h 60 to calculate the total repair bill, f(h), for h number of hours worked. find h if f(h) = $150. 1 hour 3 hours 4,500 hours 4,560 hours

The total cost for the repair is expressed as f(h) = 30h + 60 where h is the number of hours worked. We are given the total cost which will allow us to calculate the number of hours worked. We calculate as follows:

 f(h) = 30h + 60
150 = 30h + 60
90 = 30h
h = 3 hours >OPTION 2.
