Given the equations:

P = 510 - 3Q

TC = 300 + 30Q + 0.2Q²

Where P = price

Q = quantity

TC = total cost

1. Marginal revenue (MR) is computed as

A. MR = 210 - 3Q	C. MR = 510 - 3Q
B. MR = 210 - 6Q	D. MR = 510 - 6Q

1. Marginal cost (MC) is computed as

A. MC = 30 + 0.2Q	C. MC = 30 + 0.4Q
B. MC = 330 + 0.4Q	D. MC = 330 + 0.2Q

1. The maximum profit, given these two equations, is

A. 21,375	C. 13,675
B. 17,700	D. 16,200
