Answer:
More than $1500 price per car per month has to be dropped.
Explanation:
Given:
price per car = $20,000
car sale per month = 40
rate of increase in demand = 3
Solution:
Revenue R = Price × Quantity = P * Q
From the above given data
P = 20,000
Q = 40
R = P*Q
dQ/dt = 3
We have to find the rate at which the price is to be dropped before monthly revenue starts to drop.
R = P*Q
dR/dt = (dP/dt)Q + P(dQ/dt)
= (dP/dt) 40 + 20,000*3 < 0
= (dP/dt) 40 < 60,000
= dP/dt < 60000/40
= dP/dt < 1,500
Hence the price has to be dropped more than $1,500 before monthly revenue starts to drop.
