Consider an industry with identical firms. Suppose the cost function of firm i, i=1,...,n, is given by Ci(qi) = 12 qi2 + 75 If a total of Q=400 units is produced efficiently in this industry, what will be the industry total cost of these 400 units? (As usual, you must enter a number below, not a ratio, not an expression with symbols..., just a number. Don't round, even if rounding makes sense... ).
