Answer to Problem 9.7P
The equilibrium
Explanation of Solution
The
Equilibrium is a point where the demand and supply curve meet. Hence this point will be,
Hence the equilibrium price is $120. Now substitute this value in above equation, we get,
Hence the equilibrium quantity is 400 units. Now the total expenditure is calculated as follows,
Now the consumer surplus is calculated by as follows,
Hence the consumer surplus is $16,000.
Now the producer surplus is calculated below,
Hence, the producer surplus is $20,000.
Introduction:Consumer surplus is a difference between the amount which consumer actually pays and the amount which he is willing to pay.
Producer surplus is the difference between what the consumer is willing to accept for a given quantity of money or good and the how much a person actually receives by selling the good in the market at the prevailing prices.

To describe: The total loss in consumer surplus and producer surplus, provided some values are changed.

Answer to Problem 9.7P
Hence the new consumer surplus is $12,000 and new producer surplus is $15,000.
Explanation of Solution
Suppose Q= 300, the total consumer surplus is calculated as follows,
=
Thus the new consumer surplus is $12,000 and it is decreased by the amount of $4,000. Now the producer surplus is calculated by as follows,
Thus the new producer surplus is $15,000 and it is decreased by the amount of $5,000.
Introduction: Consumer surplus is a difference between the amount which consumer actually pays and the amount which he is willing to pay.
Producer surplus is the difference between what the consumer is willing to accept for a given quantity of money or good and the how much a person actually receives by selling the good in the market at the prevailing prices.
c.
To describe: The allocation of producer and consumer surplus between suppliers and demanders are dependent upon the price at which broccoli is sold.
c.

Answer to Problem 9.7P
As the equilibrium price increases, consumer surplus will decreased by $7,000 and producer surplus will increased by $8,800. If price will be $95 then producer surplus is decreased by $8,750 and consumer surplus is decreased by $11,562.50.
Explanation of Solution
Let the equilibrium price P = $140, then consumer surplus is calculated as follows,
As the equilibrium price is increased, the consumer surplus will decreased by $7,000.
Now the producer surplus will be,
As the equilibrium price is increased, producer surplus will increased by $8,800.
Now assume the equilibrium price is $95 then the consumer surplus will be,
Thus consumer surplus is decreased by $11,562.50. Now the producer surplus will be,
Thus, the producer surplus is decreased by $8,750.
Introduction: Consumer surplus is the difference between the amount a consumer spends to purchase a commodity versus the amount he willingly wants to spend on the purchase.
Producer surplus is the difference between what the consumervoluntarily want to accept for a particular amount quantity of money or quantity of good and how much a person actually generates by selling the good in the market at the existing prices.

Answer to Problem 9.7P
Thus the consumer surplus is increased by $2,000 and producer surplus is increased by $2,500.
Explanation of Solution
Let
Thus the consumer surplus is increased by $2,000. Now calculate the producer surplus,
Thus the producer surplus is increased by $2,500.
Introduction: Equilibriumpoint is that point at which demand and supply curve cut each other. At equilibrium quantity demanded is always equal to quantity supplied.

Answer to Problem 9.7P
The graphs of all the results are given below.
Explanation of Solution
Here, the price shows in Y-axis and quantity shows in X-axis. Here fig (a) shows the equilibrium point at 400 and the equilibrium price is $120. The fig (b) shows that the equilibrium price is reduced to 300 from 400. The blue area shows the loss. The fig (c) shows the variation in equilibrium price from $120 to $95. The fig(d) represents the increased quantity from 300 to 450.

Plan 2: Johnny receives a $400,000 fixed recording fee and zero royalty per CD sold. Under either plan, the record company will choose the price of Johnny's CD so as to maximize its (the record company's) profit.
