Carl's Jr $70 2 per hour to mow lawn plus an additional $5 to cover the cost of gasoline how much will Carlos charge if he works for four and a half hours
f(x) = (70 x 4.5) + 5 You then get 315 from multiplying 70 and 4.5. Then add the additional 5 from gasoline. You end up with 320$ for working 4 and a half hours
