A firm with a $14\%$ WACC is evaluating two projects for this year's capital budget. After$-$tax cash flows, including depreciation, are follows:

project M

Project N

$m-9,000$

$m-3,000$

$N-$$$27,000$ $$8,400$

$m$$$3,000$

$n$$$8,400$

$m$$$3,000$

$n$$$8,400$

$m$ $$3,00$

$n$ $$8,400$

$m$ $$3,000$

$n$ $$8,400$

b$.$ Assuming the projects are independent, which one$($s$)$ would you recommend?

$-$Select$-$

c$.$ If the projects are mutually exclusive, which would you recommend?

$-$Select$-$

d$.$ Notice that the projects have the same cash flow timing pattern. Why is there a conflict between NPV and IRR?
