A firm has a new project with an initial investment of $$60,000$ and the following end$-$of$-$year estimated cash flows:

Year $1$: $$28,000$

Year $2$: $$18,000$

Year $3$: $$30,000$

Year $4$: $$30,000$

If the firm's appropriate WACC $=6\%,$ what is the Modified Internal Rate of Return $($MIRR$)$ of this project?
