Question

If the monopolist's marginal revenue curve is MR = 30 - 6Q,the marginal revenue of the third unit of output is

Quizplus · Accepted Answer

The third unit of output means Q=3. 
Substituting Q=3 into MR = 30 - 6Q gives: 
MR = 30 - 6(3) 
MR = 30 - 18 = 12 
Therefore, the marginal revenue of the third unit of output is $12.
