Bob Edwards owns a bagel shop.Bob hires an economist who assesses the shape of the bagel shop's average total cost (ATC)curve as a function of the number of bagels produced.The results indicate a U-shaped average total cost curve.Bob's economist explains that ATC is U-shaped for two reasons.The first is the existence of diminishing marginal product,which causes it to rise.What would be the second reason? Assume that the marginal cost curve is linear.(Hint: The second reason relates to average fixed cost)
