Question

Connor has hired two painters to paint his house. The first painter charges $12 an hour and the second painter charges $11 an hour. It will take 15 hours of labor to paint the house. A. Wrote a polynomial to represent the total cost of the job if the first painter does x hours of work. B. Write a polynomial to represent the total cost of the job if the second painter does y hours of labor.

Answer 1

Answer:

Cost = cost of first painter + cost of second painter

      = $12/hr * hours worked  + $11 * hours worked

   where x is the hours the first painter works

C(x) = 12 x + 11 ( 15 - x)

       = 12 x + 165 - 11x

        = x + 165

C(x,y) = 12 x + 11 y

   where y = 15  - x because the total hours is 15
