a) A firm in a operating in Perfect competition are a price taker . so they cannot influence the market price niether they can charge thier own profit maximizing price. so they choose the market price and hence market price is the marginal revenue for perfect competiion firm and they choose the output where MR =MC or P =MC. so the profit maximizing price of perfect competition firm is $100 per unit.

b) A profit - maximizing quantity is the quantity where the MR=MC. or P=MC because for a perfect comeptition firm P=MR.

100 = 25 + 0.5q

100 -25 = 0.5q

75 = 0.5q or q = 150

so profit maximizing quantity is 150 units.
