Consider the cost schedule given in the following table and P = $26 for a perfectly competitive firm:
Output Total Variable Costs Total Costs (STC)
0 $0 $30
1 20 50
2 30 60
3 48 78
4 90 120
5 170 200
Draw three separate graphs using the SATC, AVC, and SMC curves, and on each one indicate (i) the profit maximizing level of output, (ii) the profit/loss per unit, (iii) the total profit/loss, and (iv) whether the firm should stay open or shut down (and why) when:
P = $42
P = $18
P = $12.50
The formulas used
ATC=TC/Q, MC = Change in TC/Change in Q, MR=P = AR, MR = Change in TR/Change in Q, TR = P*Q, Profits = TR-TC
