Current Attempt in Progress

Galvanized Products is considering purchasing a new computer system for their enterprise data management system. The vendor has quoted a purchase price of $$80,000.$ Galvanized Products is planning to borrow $\frac{1}{4}$ th of the purchase price from a bank at $18\mathrm{.}00\%$ compounded annually. The loan is to be repaid using equal annual payments over a $3-$year period. The computer system is expected to last $5$ years and has a salvage value of $$4,800$ at that time. Over the $5-$year period, Galvanized Products expects to pay a technician $$23,000$ per year to maintain the system but will save $$57,000$ per year through increased efficiencies. Galvanized Products uses a MARR of $15\mathrm{.}00\frac{\%}{?}$ year to evaluate investments.
