According to an article in the New York Times, in 2014 Chipotle Mexican Grill experienced an increase in the cost of the beef used in its beef burritos. Draw a graph showing the effect of this increase on the price of Chipotle's burritos and on the quantity of burritos Chipotle sells. Be sure that your graph includes Chipotle's demand, marginal revenue, marginal cost, and average total cost curves. Your graph should show changes in any of the curves.
