Suppose Extensive Enterprises$$s CFO is evaluating a project with the following cash inflows. She does not know the project$$s initial cost; however, she does know that the project$$s regular payback period is $2\mathrm{.}5$ years.

Year

Cash Flow

Year $1$ $$300,000$

Year $2$ $$500,000$

Year $3$ $$425,000$

Year $4$ $$425,000$

If the project$$s weighted average cost of capital $($WACC$)$ is $8\%,$ what is its NPV$?$
