5. A monopolist faces the total revenue schedule TR = 4350q - 13q2 and the total cost schedule TC = 93 – 5.5 q2 + 150 q. Find it's profit-maximizing level of output. In a graph, draw its average revenue (AR), marginal revenue ( MR) and marginal cost (MC) functions and indicate the profit-maximizing level of output and price.
My algebra course does not allow for calculators, how would i
solve both parts of this problem step by step?
