According to an article in the Wall Street Journal, in 2015 and 2016, Panera suffered from lower profits in part because of the costs of implementing its “clean food” strategy. Draw a graph showing the effect of this cost increase on the price of Panera’s turkey sandwiches, on the quantity of turkey sandwiches Panera sells, and on its profit. Be sure that your graph includes Panera’s demand, marginal revenue, marginal cost, and average total cost curves. Your graph should show changes in any of the curves. For simplicity, assume that Panera’s clean food strategy doesn’t affect the demand for its turkey sandwiches.
