An electronics firm invested $50,000 in a precision inspection device . They spend $1500 each year to operate and maintain it. An additional $750 is spent in years 2 and 4 for software updates. At the end of 5 years, the firm changed their inspection procedure, eliminating the need for the device.

Assume interest at 10% per year.
