The screen captures in Exercises 39–46 show a matrix, A, corresponding to a system of linear equations and the matrix rref ( A ) obtained after the Gauss–Jordan elimination method is applied to A. Write the system of linear equations corresponding to A, and use rref ( A ) to give the solution to the system of linear equations.

a. At 60 units of output, how much would this profit-maximizing monopolist charge?
b. How many units would it produce to maximize total revenue rather than total profit?
c. What is the maximum quantity this firm can produce without incurring economic losses?
d. Calculate the firm's profit at the profit-maximizing output and price.
e. Why is this firm's marginal revenue curve below its demand curve? Explain.
