Question

Help plz thanks question 1

Answer 1

-2x^2 + 500x - 350

You need to plug in the equations for C(x) and R(x) into the equation P(x)= R(x) - C(x) and solve.

Answer 2

We will do exactly what the question asks and we will Subtract C(x) from R(x) to discover P(x):

P(x) = R(x) - C(x)
P(x) = ($-2x^{2} + 900x - 200$) - ($400x + 150$)
P(x) = $-2x^{2} + 900x - 400x + 150 - 200$
P(x) = $-2x^{2} + 500x - 50$

Hope this helps!
