Investment A is considered to be typical of the firm$$s investments. Investment B$$s cash flows vary over time but are considered to be less certain. Investment C$$s cash flows diminish over time but because most of the cash flows occur early in the investment$$s life, they are considered to be more certain. The firm$$s cost of capital is $10$ percent, but the financial manager uses a hurdle rate of $6$ percent for less$-$risky projects and $14$ percent for riskier projects. Use Appendix B and Appendix D to answer the questions. Assume that the investments are not mutually exclusive and there are no budget restrictions.
