we want to donate a marble birdbath to the city park as a memorial to cats. we also want to set up a perpetual care fund to cover future expenses "forever". the initial cost of the bath is $5000. routine annual operating costs are $200 per year, but every fifth year the cost will be $500 to cover major cleaning and maintenance as well as operation. a) what is the capitalized cost of this project if the interest rate it 8%? b) hoe much is the present worth of this project if it is to be demolished after 75 years? the final $500 payment in the 75th year will cover the year's operating cost and the site reclamation. explain your work please
