i.
Book Value after 2 years.

Answer to Problem 51P
Book Value after 2 years is $40800.
Explanation of Solution
Given:
Useful Life = 5 years
Cost of asset = $85000
Salvage Value = $15000
ADR life = 8 years.
Calculation:
MACRS
Recovery Year, t (year) | MACRS |
1 | 20% |
2 | 32% |
3 | 19.20% |
4 | 11.52% |
5 | 11.52% |
6 | 5.76% |
100% |
The asset is a 5-year property with asset depreciation range (ADR) class life of more than 10 years and less than 16 years.
Book Value is calculated of an asset at the end of 1st year of its useful life period.
T = 1
B = $85000
Years | Depreciation charge | Book Value |
1 | 17000 | 68000 |
2 | 27200 | 40800 |
3 | 16320 | 24480 |

vi.
Book Value at the end of 3rd year using straight Line Method.

Answer to Problem 51P
The book value of the asset after 3rd year is $58570.
Explanation of Solution
Given:
Useful Life = 5 years
Cost of asset = $85000
Salvage Value = $15000
ADR life = 8 years.
Calculation:
Straight Line depreciation Method:
T = 1 year
B = $85000
S = $15000
N = 8
Straight Line depreciation is constant throughout the depreciable Life. Thus, the depreciation charge for the asset is $8750 for every year throughout the depreciable life of the asset.
Book Value at the end of 3rd year
Conclusion:
Thus, the book value of the asset after 3rd year is $58570.
vi.

Explanation of Solution
Given:
Useful Life = 5 years
Cost of asset = $85000
Salvage Value = $15000
ADR life = 8 years.
Calculation:
Conclusion:
Thus, the book value of the asset after 8th year is $15000.

- Title: Does the educational performance depend on its literacy rate and government spending over the last 10 years? In the introduction, there are four things to include:a) Clearly state your research topic follows by country’s background in terms of (population density; male/female ratio; and identify the problem leading up to the study of it, such as government spending and adult literacy rate. How does the US perform compared to other countries.b) State the research question that you wish to resolve: Does the US economic performance depend on its government spending on education and the literacy rate over the last 10 years. Define performance (Y) as the average income per capita, an indicator of the country’s economy growing over time. For example, an increase in government spending leads to higher literacy rates and subsequently higher productivity in the economy. Also, mention that you will use a sample size of 10 years of secondary data from the existing literature,…arrow_forwardTitle: Does the educational performance depend on its literacy rate and government spending over the last 10 years?

BY VIRGINIA POSTREL WOULD you rather have $1,000 for sure or a 90 percent chance of $5,000? A guaranteed $1,000 or a 75 percent chance of $4,000? In economic theory, questions like these have no right or wrong answers. Even if a gamble is mathematically more valuable a 75 percent chance of $4,000 has an expected value of $3,000, for instance someone may still prefer a sure thing. People have different tastes for risk, just as they have different tastes for ice cream or paint colors. The same is true for waiting: Would you rather have $400 now or $100 every year for 10 years? How about $3,400 this month or $3,800 next month? Different people will answer differently.
