If a firm’s marginal cost is MC = 4 +4q and market price is $8, what is the profit maximising level of output (assuming the firm produces a positive quantity)?

The profit maximising output of a competitive firm is given as, MR=MC. This may also be written as;Group of answer choicesP=ACP=MCMR=PMR=AC

Barbara has estimated the demand and marginal revenue for her product.They are P = 84 - 2Q (quantity) and MR = 84 - 4Q, respectively.She also experiences a constant marginal cost of $16.What is Barbara’s profit-maximising quantity and price?Question 4Answera.Q = 12; P = $50b.Q = 12; P = $40c.Q = 17; P = $50d.Q = 17; P = $40

he algebraic expression MR=MC suggests thatGroup of answer choicesmarginal profit is decreasing.marginal profit is increasing.marginal profit is maximum.marginal profit is zero.

Refer to Scenario 15.5. Suppose there are 100 firms each with a short run total cost of TC = q2 + q + 4, so that marginal cost is MC = 2q +1. If market demand is given by QD = 1050 − 50P, how much will be produced in the market ( Call this Q)?  and what profit will each firm make?Group of answer choicesQ=300, Profit = $25Q=400, Profit = $15Q=500, Profit = $21Q=600, Profit = $50

Suppose that at the current output level the price received by a monopolist for its good is $10, marginal revenue is equal to $6, and marginal cost is $8. To maximise profit the monopolist should: A. decrease output B. increase output C. keep output constant D. we cannot say without more information
