- **d. Selection of Alternatives:**  
  Identify which investment alternatives should be selected given the conditions outlined.

- **e. Present Worth Calculation:**  
  Determine the present worth of the optimum investment portfolio.

- **f. IRR Calculation:**

- **g. Determine the Optimum Portfolio with Varied Capital Limits:**  
  Identify the optimum portfolio (including selected investments and their present worth) using the following capital limits: (1) the current limit on investment capital, (2) a limit increased by 20%, and (3) a limit decreased by 20%.

- **h. Determine the Optimum Portfolio with Varied MARR:**  
  Identify the optimum portfolio (stating the investments selected and their present worth) using the following Minimum Attractive Rate of Return (MARR): (1) the current MARR, (2) a MARR of 14.4%, and (3) a MARR of 9.6%.

**12.02-PR004** CustomMetalworks is considering the expansion of their cable fabrication business for towers, rigging, winches, and many other uses. They have available $250,000 for investment and have identified the following *indivisible* alternatives, each of which will provide an exit with full return of the investment at the end of a 5-year planning horizon. Each year, CustomMetalworks will receive an annual return as noted below. MARR is 12%.

| Investment | Initial Investment | Annual Return |
|------------|--------------------|---------------|
| 1          | $25,000            | $7,500        |
| 2          | $40,000            | $12,000       |
| 3          | $85,000            | $20,000       |
| 4          | $100,000           | $22,000       |
| 5          | $65,000            | $17,000       |

For the original problem:

a. Which alternatives should be selected by CustomMetalworks?

b. What is the present worth for the optimum investment portfolio?

c. What is the IRR for the optimum investment portfolio?
