Explanation / Answer

Firm's fixed cost is $1 because that is cost incurred at 0 production.

Fertilizers and seeds are the examples of Fixed cost.

b) In perfect competition, quantity is where MR=MC. MC = 7 at Quantity of 5 units. (TC5 - TC4 = 22-15)

Answer is 5.

c) MC = 5, this happens at quantity 3 i.e. TC3-TC2=5.

Answer is 3.
