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
