Actuarial math
An industrialist is considering the purchase of a new machine for $50000. If purchased, the machine can be used to convert $1000 of raw materials at the beginning of each year into widgets than can be sold for $9000 at the end of each year. The machine will last for 10 years, and it is worthless thereafter.
The required rate of return is an annual effective rate of 8%.
Calculate the net present value of purchasing the machine and operating it for 10 years.
