1. A firm is a monopolistic producer of two goods. The prices are related to quantities Q1 and Q2 according to the demand functions P = 50- Q1 and P2 95 -3Q2. If the total cost function is TC = Q? + 3Q,Q2 + Q², i) Find the firm's total revenue function. ii) Find the firm's total profit function. iii) Calculate the values of Q1 and Q2 which maximize profit. iv) Using the second order condition (SOC), prove that the profit level is at a maximum.

1.
A firm is a monopolistic producer of two goods. The prices are related to quantities Q1
and Q2 according to the demand functions P = 50 – Q, and P = 95 – 3Q2. If the
total cost function is TC = Qf + 3Q,Q2 + Qź,
i)
Find the firm's total revenue function.
ii)
Find the firm's total profit function.
iii)
Calculate the values of Q, and Q2 which maximize profit.
iv)
Using the second order condition (SOC), prove that the profit level is at a
maximum.
