Aerotron Electronics is considering purchasing a water filtration system to assist in circuit board manufacturing. The system costs
$40,000. It has an expected life of 7 years, at which time its salvage value will be $7,500. Operating and maintenance expenses are
estimated to be $2,000 per year. If the filtration system is not purchased, Aerotron Electronics will have to pay Bay City $12,000 per
year for water purification. If the system is purchased, no water purification from Bay City will be needed. Aerotron Electronics must
borrow half of the purchase price, but they cannot start repaying the loan for 2 years. The bank has agreed to three equal annual
payments, with the first payment due at the end of year 2. The loan interest rate is 8% compounded annually. Aerotron Electronics'
MARR is 10% compounded annually.
