Answer:
The profit maximizing output level declines by 2.5 units and the price rises by $100.
Explanation:
In a monopoly market the inverse demand curve is given as,
P = 1,200 - 40Q
The marginal cost of production of the last unit is $200.
The total revenue is
= 
= 
The marginal revenue of the last unit is
= 
= 1,200 - 80Q
At equilibrium the marginal revenue is equal to marginal price,
MR = MC
1,200 - 80Q = 200
80Q = 1,000
Q = 12.5
Putting the value of Q in the inverse demand function,
P = 
P = $700
Now, if the marginal cost rises to $400,
At equilibrium the marginal revenue is equal to marginal price,
MR = MC
1,200 - 80Q = 400
80Q = 800
Q = 10
Putting the value of Q in the inverse demand function,
P = 
P = $800
Answer:
A. Low prices and enormous product availability.
Explanation:
This is a chain of retail stores or a retail outlet that sells different kinds of goods or products that in a way that seems cheap and affordable to consumers. They also look and facilitate quick form of buying and selling. Their main goal stands primarily on cheap, fast enormous sales of the product.
