A small heat pump now costs $2,400 to purchase and install. It has a projected useful life of 18 years and will incur annual maintenance costs of $100 per year in real (year-zero) dollars over the useful life. These costs are projected to increase at 6% per year, which is the expected general inflation rate. The annual cost of electricity for the heat pump is $700 in year-zero dollars. Electricity prices are projected to increase at an annual rate of 8%. The firm's MARR, which includes an allowance for general price inflation, is 15% per year (im). No market value is expected from the heat pump at the end of the 18 years of service life.

(Round to the nearest dollar.) b. (i) What is the AW, expressed in actual dollars, of owning and operating the heat pump? The AW is $. (Round to the nearest dollar.) (ii) What is the AW in real dollars of owning and operating the heat pump? The AW is $ : (Round to the nearest dollar.)
