solve your formula from problem 14 for h. Then find the handyman's hourly rate if his fixed rate is $20 and he charges $200for a 4-hour job

Givens

Total = T = 200

Fixed = F = 20

Hours = h = 4

Rate = r = ?

Formula

C = F + h * r

Solve

200 = 20 + 4*r Subtract 20 from both sides

200 - 20 = 4r

180 = 4r Divide by 4

180/4 = r

r = 45 dollars an hour <<< Answer
