a) Suppose a firm's demand curve is P = 100 - Q. Find MR when Q = 10.
b) Suppose a firm's demand curve is P = 50 - Q, and its total cost curve is TC = 10 + 10Q, so that its MC=10. Find its optimal (profit maximizing) quantity of output.
c) Suppose a firm's demand curve is P = 50 - Q, and its total cost curve is TC = 10 + 10Q, so that its MC=10. Find its optimal (profit maximizing) price.
d) Suppose a firm's demand curve is P = 50 - Q, and its total cost curve is TC = 10 + 10Q, so that its MC=10. Find its maximized profits.
