i.
Alternative to be selected if interest rate is 6%.

Answer to Problem 69P
Alternative A is the correct answer.
Explanation of Solution
Given:
Interest Rate is 6%
A | B | C | |
Installed Cost | $10,000 | $15,000 | $20,000 |
Annual Benefit | 1,625 | 1,530 | 1,890 |
Useful Life(yrs) | 10 | 20 | 20 |
Concept used:
Calculation:
Net Present worth analysis of Option- A
Formula used to calculate the present worth is given below:
Here,
P is the initial cost of the alternative ($10000)
A is the uniform annual benefit ($1625)
F1is additional investment required in replacement ($10000) (in year- 10)
I is the interest rate (6%)
Substitute the values in above formula:
PW
Thus, the present worth of the option A is $3054.75
Net present Worth Analysis of option B
Formula used to calculate the Present worth is given below:
Here,
P is the initial cost of the alternative ($15000)
A is the uniform annual benefit ($1530)
i is the interest rate (6%)
n is the time period (20 years)
Substitute the values in above formula
PW =
Thus, the present worth of the option B is $2549.10
Net Present Worth Analysis of option C
Formula used to calculate the present worth is given below:
Here,
P is the initial cost of the alternative ($20000)
A is the uniform annual benefit ($1890)
i is the interest rate (6%)
n is the time period (20 years)
Substitute the values in above formula
PW =
Thus, the present worth of the analysis C is $1678.30.
Conclusion:
Using the present worth analysis, the best alternative is alternative A as the present worth of alternative A is highest among three options.
Thus alternative A is the correct answer.
ii.
Best alternative is selected.

Answer to Problem 69P
Alternative A is selected.
Explanation of Solution
Given:
Interest Rate is 3%.
Concept used:
RATE OF RETURN: It is a return which usually an investor gets on speculation. Investment can be done on shares, bonds etc. If rate of return is calculated for a fiscal year, then it is termed as annual rate of return.
Calculation:
