(a) Your buddy in mechanical engineering has invented a money machine. The main drawback of the machine is that it is slow. It takes one year to manufacture $1300. However, once built, the machine will last forever and will require no maintenance. The machine takes one year to build and it will cost $26000 to build. Your buddy wants to know if he should invest the money to construct it. If the interest rate is 4.0% per year, what should your buddy do? Calculate the NPV.

The NPV of the machine is $. (round to the nearest dollar)

(b) Your buddy has found a way to improve the machine. Everything else equal as in (a), the amount of produced money will increase every year by 1%. Calculate the NPV for this improved machine.

The NPV of the machine is $. (round to the nearest dollar)

(c) Your buddy is interested to know the IRR for (b).

The IRR of the machine is %. (round to 2 decimal places)
