(a) Find the average rate of change of total cost when production changes from 100 to 200 printers. (b) Find the average rate of change of total cost when production changes from 200 to 600 printers. (c) Interpret the results from parts (a) and (b). The average rate of change of price per printer is greater when 200 to 600 printers are produced. O The average rate of change of total cost of production is greater when 200 to 600 printers are produced. The average rate of change of price per printer is greater when 100 to 200 printers are produced. O The average rates of change of total cost of production are equal. The average rate of change of total cost of production is greater when 100 to 200 printers are produced. Need Help? Read It Submit Answer 2. [-/2 Points] DETAILS HARMATHAP12 9.3.001.
