Marsha Jones has bought a used Mercedes horse transporter for her Connecticut estate. It cost $44,000. The object is to save on horse transporter rentals.

Marsha had been renting a transporter every other week for $209 per week plus $1.45 per mile. Most of the trips are 90 miles in total. Marsha usually gives the driver a $30 tip. With the new transporter she will only have to pay for diesel fuel and maintenance, at about $.54 per mile. Insurance costs for Marshas transporter are $1,650 per year.

The transporter will probably be worth $24,000 (in real terms) after eight years, when Marshas horse Nike will be ready to retire.

Hint: All numbers given in the questions are in real terms. Assume CF at end of year, for simplicity.
