Question 980734: I really need help with this Problem.
At Allied Electronics, production has begun on the X-15 Computer Chip. The total revenue function is given by R(x)=40x-0.3x^2 and the total cost function is given by C(x)=9x+16 where x represents the number of boxes of computer chips produced. The total profit function, P(x), is such that P(x)=R(x)-C(x). Find P(x)
a) P(x) = -0.3x^2 + 22x + 16
b) P(x) = 0.3x^2 + 22x - 48
c) P(x) = 0.3x^2 + 31x - 32
d) P(x) = -0.3x^2 + 31x - 16

We are given

R%28x%29 = 40x - 0.3x%5E2     and     C%28x%29 = 9x + 16.

We need to find  R%28x%29 - C%28x%29.

R%28x%29 - C%28x%29 = -0.3x%5E2 + %2840x+-+9x%29 - 16 = -0.3x%5E2 + 31x - 16.

Answer  d)  is correct.
