Assume that the project is expected to return monetary benefits of $$20,000$ the first year, and increasing benefits of $$5,000$ until the end of project life $($year $1=$$$20,000,$ year $2=$$$25,000,$ year $3=$ $$30,000).$ The project also has one$-$time costs of $$30,000,$ and fixed recurring costs of $$10,000$ until the end of project life. The project has a discount rate of $8\%$ and a three$-$year time horizon.

Calculate overall net present value $($NPV$)$ of the project at the end of project life. Enter only the numeric value without comma $(,)$ or dollar $($$$)$ signs.
