An automobile manufacturer can produce up to 300 cars per day. The profit made from the sale of these vehicles can be modeled by the function P(x)=−10x2+1,900x−34,000,P(x)=−10x2+1,900x−34,000, where P(x) is the profit in dollars and x is the number of automobiles made and sold. How many cars should be made and sold to maximize profit? Select one: 45 95 190 1,900
