As Senior Accountant, you can use the net present value $($NPV$)$ and internal rate of return $($IRR$)$ methods to evaluate the

profitability of the two investment opportunities $.$

To calculate the NPV$,$ you need to discount the expected cash inflows of each project by the desired rate of return $(8$ percent$)$ and

subtract the initial cash expenditures. The project with the higher NPV is the preferred method of investment.

For Project A$,$ the NPV can be calculated as follows:NPV $=-160,000+(52,800/(1+0\mathrm{.}08)^1)+(52,800/(1+0\mathrm{.}08)^2)+(52,800/(1+0\mathrm{.}08)^3)+(52,800/(1+0\mathrm{.}08)^4)$
