question
Assume the Unico Corporation is producing 40 units of output and selling the output in a perfectly competitive market for $5 per unit. Its total fixed costs are $110 and its average variable cost is $4 for each of the 40 units of output. Unico:
A.earns a profit of $40.
B.maximizes its profits.
C. earns a loss of $70.
D. should shut down.
A.earns a profit of $40.
B.maximizes its profits.
C. earns a loss of $70.
D. should shut down.
answer
C. earns a loss of $70
TFC=110
40*4=160
160+110=270
270-200= $70
TFC=110
40*4=160
160+110=270
270-200= $70
