Green Power Company is considering buying a new machine that will last for $12$

years. The machine cost $154,932$ dollars today. Maintenance expenses will be

$21,531$ dollars the first year, and will increase by $6,193$ dollars every year

afterward $($e$.$g$.$ maintenance at the end of year two is equal to $21,531$ plus $6,193$

dollars$).$ The interefic rate is $9\%$ per year, compounded annually. What is the net

present value $($NPV$)$ of this machine? Assume all maintenance expenses occur at

the end of every year. $($note: round your answer to two decimal places; do not

include spaces or dollar signs.$)$
