Answer:
A) Marginal private cost= 50
B) Total Marginal social cost to society = 70
Explanation:
A) In order to find the marginal private cost we will use the firms production cost formula as it is the private cost that the firm is enduring and is only relevant to the firm's cost and not the society's cost.
In order to find the marginal unit cost of the 10th unit produced will will replace Q in the formula by 10 as it represents quantity.
MC= 10 + 4Q
MC= 10 + 4(10)
MC= 10 +40 = 50
B) In order to find the marginal cost to society we will add the marginal external cost of the 10th unit to its private cost. We already know the marginal private cost is 50 now we need to find the marginal external cost to it to find the total marginal cost.
Marginal external cost = 2Q
Q= 10
Marginal external cost = 2*10 =20
The total Marginal cost to society= 50 + 20= 70

If the government wants to expand aggregate demand, it can "rebate" government purchases or "cut" taxes.
<h3>What is aggregate demand?</h3>
The total quantity of demand for all finished products and services generated in an economy is measured as aggregate demand.
Some characteristics of aggregate demand are-
- The total amount of money spent on those goods and services at a particular price level and time is known as aggregate demand.
- The correlation between output and all prices can be seen on an aggregate demand curve.
- In the end, the aggregate demand curve slopes downward because it predicts a fall in real gross domestic product (GDP) as prices rise.
- Consumer spending, investment spending, government spending, and the difference between exports and imports are all added together to determine aggregate demand.
- When one of these variables changes but the overall supply stays unchanged, aggregate demand will alter.

Answer:
decrease
Explanation:
Marginal cost is a concept that explains the cost a company has to produce one more unit of good. This is a measure that is associated with the productivity of the inputs used in the production process. When a company increases production, marginal cost tends to decrease as inputs are better utilized. This is because the company specializes in production in order to streamline inputs and increase productivity.
