Due to an excess of unsold units in April, the number of gaming consoles a manufacturer needs to produce in May is given by the function f(x) = x - 400, where x represents the number of new units produced in May. The manufacturer's profit per unit for May decreases due to the excess, and is given by the function g(x) = 1,200 - 2x. Which function best describes the total profit the manufacturer can earn in May, P(x)? A. P(x) = -x2 + 1,000x - 240,000 B. P(x) = -2x2 + 2,000x - 480,000 C. P(x) = -x2 + 800x D. P(x) = -2x2 + 400x - 480,000
