(b) What level of production will produce a minimum average cost per unit?

3.A corporation manufactures a product at two locations. The cost functions for producing x1 units at location 1 and x2 units at location 2 are C₁=0.05x₁²+15x₁+5400 and C₂=0.03x₂²+15x₂+6100 respectively. The demand function for the product is p=225-0.4(x1+x2). Find the production levels at the two locations that will maximize the profit.
