A company is considering a project which requires $$4\mathrm{.}1$ million in capital investment. The project can bring in an

annual revenue of $$150\frac{k}{?}$ yearsover the next $10$ years. The annual operation cost $($e$.$g$.$ labor and supplies$)$ is $$47\frac{k}{?}$ year.

Starting from year $5,$ the equipment will need major maintenance and this cost starts at $$15\frac{k}{y}$ear and increase by

$$15k$ each year until the end of the project life time $(10$ years$).$ The equipment has a salvage value of $$410k$ at the end

of the project. Calculate the project's net future value at year $10$ to find out whether it's worth investing. The interest

rate is $7\%.$

Please only fill in the number of your calculated result in the blank, e$.$g$.,$ if the result is $$100k,$ fill in $"100"$; also round

to the nearest integer."
