FUN will need high$-$tech $3$D printers on an ongoing basis. You are considering two models. Model $1$ costs $$14,000$ and is expected to run for $5$ years. Model $2$ costs $$17,000$ and is expected to run for $9$ years. The maintenance costs each year are $$1,300$ for Model $1$ and $$900$ for Model $2.$ Assume after tax cash flows and that the weighted average cost of capital $($WACC $-$ Possibly $10\mathrm{.}4\%)$ is what you calculated in Question $1.$ Which model should FUN buy?
