(2) Suppose that the prot (in hundreds of dollars) of a supermarket is approximated by 13(3), .9) = 2000 + 303; 23:2 + 1003,! _ 3,2, where cc is the cost of a unit of labor, and y is the average cost of a unit of goods. Find the values of :1; and 3; that maximize the prot. Find the maximum prot. Use the Second Derivative Test to indicate if the critical numbers give maximums or minimums
