Demand function P=50-Q
Average Cost 5Q + 40 +10/Q

Calculate the firm's total cost function

Find the marginal cost function and evaluate it at Q=2 and Q=3

What is the total revenue function

Find the firms's revenue maximising output level

Find the firm's profit function

Take a shot. What do you think the firm's cost and revenue functions are?

I thought maybe you could say the cost is 5Q + 40 + 10 but only on the basis that the average cost is divided by Q

My problem is I don;t understand the relationship between all the functions so no idea how to find the revenue function
