of heavy machinery to replace an old, outdated machine that is

currently used in its business operations. The new machine will

cost $$180,000$ and is expected to last $8$ years. The new machine

would require a repair of $$7,500$ in year three and another

repair costing $$25,000$ in year seven. The new machine has a

salvage value at the end of eight years of $$15,000.$ The old,

outdated machine costs $$150,000$ per year to maintain and run.

The new machine is only expected to cost $$90,000$ per year to

maintain and run. M$.$T$.$ Glass has a cost of capital of $15\%$ and

an income tax rate of $40\%.$

Calculate the net present value $($NPV$)$ of the new machine. If

your answer is negative, place a minus sign in front of your

answer with no spaces in between $($e$.$g$.,-1234).$
