Explanation:
It is an simplified version which makes us to understand and observe the "economic behavior"
It purely uses mathematical concepts and simplify the information and show only important or highlighting information.
You can alternatively use "economic theory" instead of "economic model"
A good economic model, will make the user to understand the complex information with the help of key pointers.
There are 2 broad classification of Economic model:
1. Theoretical
2. Empirical.
The commonly used economic model is the classic model, which constitutes of "The law of demand and the law of supply"
Answer:
Gross Domestic Product
= $500
<em>GDP is the final value of goods and services. The haircut is valued at $500 so is GDP. </em>
Net National Product:
= GDP - Depreciation
= 500 - 80
= $420
National Income
= $420
<em>This is the income that a resident of the country earns and $420 is what Barry earned in net income.</em>
Personal Income
= National income - Retained earnings
= 420 - 120 - 50
= $250
Disposable Personal Income (Dollars)
= Personal income - income taxes
= 250 - 90
= $160
Answer:
During the first year, the marginal cost equals approximately the minimum EUAC cost. This is why the minimum cost of EUAC to maintain the defender throughout the year is $21,000. Since the minimum EUAC cost to maintain the defender the first year is less than the minimum EUAC cost to the challenger, the defender should not be substituted. This means, it is not economically feasible to make the replacement at this time.
Explanation:
According to the exercise, it is necessary to evaluate to know if it is economic to replace the defender by the challenger. For the calculation, the defender's information is: the defender's market value up to $3000. The expenses are $20000. The information regarding the challenger is: the installation cost $30000, the annual expenses $ 16000, the surrender value $ 2000, the economic life is 12 years, and the interest rate before taxes is 15%.
The minimum EUAC for the challenger is equal to:

The minimal cost is equal to:
