The question doesnt seem to be repeated. From here, I'm just going to assume the hours he worked is 4. Heres what the equation would look like.

4x + 4 = r

r = total money earned
x = cost per hours worked
The plus 4 is the flat fee he charges,

Answer:

$9327

Step-by-step explanation:

Apparently, the cost function is supposed to be ...

C(x) = 0.4x^2 -112x +17167

This can be rewritten to vertex form as ...

C(x) = 0.4(x^2 -280) +17167

C(x) = 0.4(x -140)^2 +17167 -0.4(19600)

C(x) = 0.4(x -140)^2 +9327
