a monopolist firm sees the following demand, find the marginal revenue.
Here's the same firm cost schedule find the marginal cost and based off of the data in these 2 find the monopolist equilibrium quantity and price.
quantity | total variable cost | marginal cost |
1 | $5 | |
2 | $9 | |
3 | $12 | |
4 | $14 | |
5 | $18 | |
6 | $24 | |
7 | $32 | |
8 | $42 | |
Ans: The monopolist equilibrium quantity = 3 and price = $5
