I think the answer is C. Individual work in the process accounts are maintained for each production department of manufacturing process.
because they are the ones that provide me goods and services.
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
