5. (A Firm's Profit) Suppose that a firm produces 3 types of output, using 2 types of input. Its output quantities are given by the column vector q=15,00027,00013,000 and their unit prices are given by p=10125 The amounts of inputs the firm uses are given by the column vector z=[11,000 30,000]. and the input prices by w=[208]. Using these data, find the expression of the firm's profit in a matrix form and compute the profit..
