Respuesta :

Answer:

a.  MR = 2/3P

b. The prom-maximizing price is $30.

Explanation:

a.  MR = P(1 + 1/e)

          = P(1 - 1/3)

          = 2/3P

Therefore, Thefirm‘s marginal revenue as a function of its price is    MR = 2/3P

b. monopoly firm maximizes profit when MR = MC

2/3P = 20

P = $30

Therefore, The prom-maximizing price is $30.
