$($Payback period, net present value, profitability index, and internal rate of return calculations$)$ You are considering a project with an initial cash outlay of $$83,000$ and expected cash flows of $$22,410$ at the end of each year for six years. The discount rate for this project is $10\mathrm{.}1$ percent.

a$.$ What are the project's payback and discounted payback periods?

b$.$ What is the project's NPV$?$

c$.$ What is the project's PI$?$

d$.$ What is the project's IRR?

a$.$ The payback period of the project is $3\mathrm{.}70$ years. $($Round to two decimal places.$)$

If the discount rate for this project is $10\mathrm{.}1\%,$ the discounted payback period of the project is $4\mathrm{.}87$ years. $($Round to two decimal places.$)$

b$.$ The project's NPV is $

$($Rounfid to the nearest dollar.$)$ How could you do this in excel? Thanks?
