: Consider the following chart for machine I $($long$-$term$)$ and machine W $($short$-$term$)$:

Years Upfront cost YR $1$ costs YR $2$ costs YR $3$ costs

I $$32,000$ $$8,500$ $$8,500$ $$8,500$

W $$26,000$ $$13,500$ $$13,500$ $$0$

Assuming a discount rate $=6\%,$ which machine will you opt for $($justify your answer: hint$-$ use the annual equivalent cost method$)?$
