(12 pts) 8) A salesperson at a used car lot is able to sell 50 used cars over an entire year. To maintain a car in the lot costs $100 over the year. To deliver a shipment of cars to the lot would cost the salesperson $100 plus an additional $250 for each car in the shipment. How many cars should the salesperson order for each shipment to minimize the maintenance cost of the cars? What is the minimum cost of reordering for the entire year
