QUESTION ONE
A monopolist's average cost function is given by
AC = 300/Q -10+Q
And its demand equation is
Q + 5P = 850;
where P and Q are price and quantity, respectively. Determine;
a. The expression for Total Revenue as a function of Q.[1.5 marks]
b. The expression for Total Cost as a function of Q. [2 marks]
