A monopolist's linear inverse demand curve is $P(Q) = 750 - 3Q$. Which of the following is the monopolist's marginal revenue? $MR = 750 - 6Q$ $MR = 1500 - 3Q$ $MR = 750Q - 6Q$ $MR = 750Q - 3Q$

Step 1
Total revenue is price times quantity, so $TR = P(Q) \times Q$. Given $P(Q) = 750 - 3Q$, we have $TR = (750 - 3Q)Q = 750Q - 3Q^2$. Show more…

Total revenue is in dollars and x is the number of units. Suppose that in a monopoly market, the demand function for a product is given by p = 480 - 0.3x where x is the number of units and p is the price in dollars. (a) Find the total revenue from the sale of 500 units. $ (b) Find the marginal revenue MR at 500 units. MR = $ Interpret this value. The 501st unit will lose |MR| hundred dollars more in revenue. The 501st unit will bring in |MR| hundred dollars more in revenue. The 501st unit will bring in |MR| dollars more in revenue. The 501st unit will lose |MR| dollars more in revenue. (c) Is more revenue expected from the 501st unit sold or from the 701st? Explain. The 701st unit will bring in $ more in revenue.

Total revenue is in dollars and x is the number of units. Suppose that in a monopoly market, the demand function for a product is given by p = 440 - 0.3x where x is the number of units and p is the price in dollars. (a) Find the total revenue from the sale of 500 units. $ 145000 (b) Find the marginal revenue MR at 500 units. MR = $ 140 Interpret this value. The 501st unit will bring in |MR| dollars more in revenue. The 501st unit will lose |MR| dollars more in revenue. The 501st unit will lose |MR| hundred dollars more in revenue. The 501st unit will bring in |MR| hundred dollars more in revenue. (c) Is more revenue expected from the 501st unit sold or from the 701st? Explain. The 701st unit will bring in $ more in revenue. Thus the --Select-- unit will bring in more revenue.

Total revenue is in dollars and x is the number of units. Suppose that in a monopoly market, the demand function for a product is given by p = 500 - 0.2x, where x is the number of units and p is the price in dollars. (a) Find the total revenue from the sale of 500 units. $ (b) Find the marginal revenue MR at 500 units. MR = $ (c) Is more revenue expected from the 501st unit sold or from the 701st? Explain. The 701st unit will bring in $ more in revenue. Thus, the
