$($O$13-2)$ Investments E and F are mutually exclusive and have physical lives of five and $10$ years, respectively. Each requires an investment $(PV$ of costs$)$ of $$5,000.$ After$-$tax annual net cash flows are $$2,400$ for $E$ and $$1,800$ for $F.$ If investment $F$ can be sold for $$2500($salvage value$)$ at the end of year $5,$ what is the net present value for investment $F$ using an $8$ percent discount rate $?$ Hints: $A=\frac{1-(1+i{)}^{-n}}{i}=\frac{1-(1+0\mathrm{.}08{)}^{-5}}{0\mathrm{.}08}=3\mathrm{.}9927$

$A=\frac{1-(1+i{)}^{-n}}{i}=\frac{1-(1+0\mathrm{.}08{)}^{-10}}{0\mathrm{.}08}=6\mathrm{.}7101$
