, answer the questions given in different scenarios: Scenario 1:
i)
Will this firm produce in the short run if the product price is $56 per unit? Why
Q = TR = TC = Total profit
= Profits
per unit = Production decision:
Scenario 2:
ii)
Will this firm produce in the short run if the product price is $41 per unit? Why?
Q = TR = TC = Total loss = Loss per unit = Production decision:
Scenario 3:
iii)
Will this firm produce in the short run if the product price is $32 per unit? Why?
Q = TR = TC = Total loss = Loss per unit = Production decision:
