An engineer is choosing between three different alternatives for a machine component he needs to complete his biorefinery. He summarized the pertinent information about these alternatives in the tables below. Assume a study period of 8 years

Alternative	Investment Cost	Salvage Value	Useful Life	Depreciation Method
A	100,000	25,000	8	Sum of the Years
B	70,000	20,000	4	Straight Line
C	76,000	5,000	6	Declining Balance

The table below shows the projected net cash flows for each of the alternatives.

EOY	Alternative A	Alternative B	Alternative C
1	30,000	-20,000	30,000
2	40,000	40,000	30,000
3	50,000	50,000	30,000
4	60,000	8,000	30,000
5	70,000	-	30,000
6	80,000	-	30,000
7	90,000	-	-
8	100,000	-	-

Note: Please take note or a screenshot of the information presented here, this will be the basis of the succeeding questions. You will not be able to go back to this page.

Upon review, assume the following changes to the above information:

A. The investment costs of Alternative B decreased to 55,000

B. The investment cost of Alternative C is reduced to 61,500. Its depreciation method is changed to Double Declining Balance.

Round all your answers to 2 decimal places, do not round intermediate solutions. For questions #7, 10, and 12, just type in the letter of the alternative.

1. What is the net cash flow for Alternative A on year 8?

2. What is the net cash flow for Alternative B on year 4?

3. What is the net cash flow for Alternative C on year 8?

Assuming a MARR of 12%, evaluate the three alternatives and recommend which among the three alternatives the engineer should invest in the AW method.

4. What is the AW of Alternative A?

5. What is the AW of Alternative B?

6. What is the AW of Alternative C?

7. Which of the three alternatives would you recommend based on the AW method?

Assuming a MARR of 8%, evaluate alternatives A and B and recommend which between the two alternatives the engineer should invest in using the FW method.

8. What is the FW of Alternative A?

9. What is the FW of Alternative B?

10. Which between the two alternatives would you recommend using the FW method?

Assuming a MARR of 6%, evaluate alternatives B and C and recommend which between the two alternatives the engineer should invest in using the PW method.

11. What is the PW of Alternative C?

12. Which between the two alternatives would you recommend using the PW method?
