At Allied Electronics, production has begun on the X-15 Computer Chip. The total revenue function is given by R(x) = 58% - 0.3x2 and the total cost function is given by C(x) = 11x + 12, 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).
