Answer:
The company maximize their profit when the marginal revenue = cost = selling price.
In this case we know that at the given price the margin revenue is 40 which do not equal the price of 15
The company should increase the price.
Step-by-step explanation:
Q = 100 - 2P
Total revenue = P x Q
total revenue = P x (100 - 2P)
total revenue = -2P^2+100P
from the total revenue we calculate the dTR/dP which is the marginal revenue:
marginal revenue = -4P + 100 = 100 - 4P
if P = 15
100 - 4 x 15 = 100 - 60 = 40
The price of 15 is below the marginal revenue.
The firm maximize their profit when the price equals the marginal revenue.
