Draw a scale diagram and plot ATC, AVC, and MC. c. Below which price should this firm choose to pro- duce zero output? d. If the market price per napkin is $0.80, what is this firm's profit-maximizing level of output? Since MC is calculated between the rows of the output levels given, state the range of output in which the profit- maximizing level of output will fall. Do the same for market prices of $0.60 and $1.00. e. Calculate the firm's profit per unit and total profit per day at an output level of 450 napkins per day and at a market price of $0.70
