a company x units of a product per month, where C(x) represents the total cost and R(x) represents the total revenue for the month. The functions are modeled by C(x) = 300x + 250 and R(x) = -0.5x^2 + 800x - 100. the profit is the difference between revenue and cost where P(x) = R(x) - C(x). What is the total profit, P(x), for the month?
