Suppose total cost in dollars from the production ofx printers is given by C(x) = 0.0001x3 + 0.005x2 + 28X + 3000. (a) Find the average rate of change of total cost when production changes from 100 to 300 printers. :] (b) Find the average rate of change of total cost when production changes from 300 to 700 printers. :] (c) Interpret the results from parts (a) and (b). O The average rate of change of total cost of production is greater when 100 to 300 printers are produced. 0 The average rate of change of price per printer is greater when 100 to 300 printers are produced. 0 The average rates of change of total cost of production are equal. 0 The average rate of change of total cost of production is greater when 300 to 700 printers are produced. 0 The average rate of change of price per printer is greater when 300 to 700 printers are produced
