suppose that the total cost function in dollars for the production of X units of a product is given by the equation shown below T C x 5760 60 x 0 1 x 2 Then the average cost of producing X items is represented by the following equation A C x frac text total cost x frac 5760 x 60 0 1 x a Find the Instantaneous rate of change of average cost with respect to the number of units produced at any level of productlon A C prime x b Find the level of production at which this rate of change equals zero X c At the value found in part b find the instantaneous rate of change of cost and find the average cost Instantaneous rate of change of cost average cost what do you notice The Instantaneous rate of change of cost equals the average cost The instantaneous rate of change of cost is greater than the average cost The Instantaneous rate of change of cost is less than the average cost
