Estimates for a proposed small public facility are as follows: Plan A has a first cost of $50,000, a life of 25 years, a $5,000 market value, and annual maintenance expenses of $1,200. Plan B has a first cost of $90,000, a life of 50 years, no market value, and annual maintenance expenses of $6,000 for the first 15 years and $1,000 per year for years 16 through 50. Assuming interest at 10% per year, compare the two plans, using the CW method.
