You must decide between two machines with different lifetimes. The first machine costs

$$170,000$ and lasts $3$ years. You will depreciate it using MACRS $(3-$year$).$ It also costs

$$48,000$ per year to operate. You will be able to sell this machine for $$20,000$ after $3$

years. The second machine costs $$540,000$ and lasts $10$ years. You will depreciate this

machine straight$-$line over its lifetime. It costs $$18,000$ per year to operate. You will be

able to sell this machine for $$45,000$ after ten years. The marginal tax rate is $34\%$ and the

appropriate discount rate is $15\%.$ What are the machines$$ equivalent annual costs

$($EACs$)$ and which do you prefer? do all of this in excel
