A firm produces two commodities, A and B. The inverse demand functions are: pA =900−2x−2y, pB =1400−2x−4y respectively, where the firm produces and sells x units of commodity A and y units of commodity B. Its costs are given by: CA =7000+100x+x^2 and CB =10000+6y^2 where A, a and b are positive constants. (a) Show that the firms total profit is given by: π(x,y)=−3x^2 −10y^2 −4xy+800x+1400y−17000. (b) Assume π(x, y) has a maximum point. Find, step by step, the production...

The market demand for a particular good in city A is given by QA = 32 − 0.5PA (for PA ≤ 64). This market is served by a single firm (monopoly) whose marginal cost of production is 4 dollars per unit (so total cost of producing Q units is 4Q). (a) Find the equation for the firm’s marginal revenue function. Graph the demand, marginal cost, and marginal revenue curves on one graph. (b) What are the profit-maximizing price and quantity...
