Marsha Jones has bought a used Mercedes horse transporter for her Connecticut estate. It cost $$47,000.$ The object is to save on horse transporter rentals.

Marsha had been renting a transporter every other week for $$212$ per day plus $$1\mathrm{.}60$ per mile. Most of the trips are $80$ or $100$ miles in total. Marsha usually gives the driver, Joe Laminitis, a $$50$ tip. With the new transporter she will only have to pay for diesel fuel and maintenance, at about $$0\mathrm{.}57$ per mile. Insurance costs for Marsha$$s transporter are $$1,800$ per year.

The transporter will probably be worth $$27,000($in real terms$)$ after eight years, when Marsha$$s horse Spike, will be ready to retire. Assume a nominal discount rate of $9\%$ and a $3\%$ forecasted inflation rate. Marsha$$s transporter is a personal outlay, not a business or financial investment, so taxes can be ignored.

Calculate the NPV of the investment.

Note: Do not round intermediate calculations. Round your answer to the nearest whole dollar amount.
