Question 195445: A perfectly competitve firm has total revenue and total cost curves given by:
TR = 100q
TC = 5000+2q+0.2Q^2
Find the profit-maximizing output

Find the maximum of the difference.
What is the maximum of TR - TC?

Take the derivative and set to 0

or plot -0.2q^2 + 98q - 5000 using your calc and find the max
