Cullumber Timur is an accounting major at a midwestern state university located approximately $60$ miles from a major city. Many of

the students attending the university are from the metropolitan area and visit their homes regularly on the weekends. Cullumber, an

entrepreneur at heart, realizes that few good commuting alternatives are available for students doing weekend travel. He believes that

a weekend commuting service could be organized and run profitably from several suburban and downtown shopping mall locations.

Cullumber has gathered the following investment information.

Five used vans would cost a total of $$75,285$ to purchase and would have a $3-$year useful life with negligible salvage value.

Cullumber plans to use straight$-$line depreciation.

Ten drivers would have to be employed at a total payroll expense of $$47,400.$

Other annual out$-$of$-$pocket expenses associated with running the commuter service would include Gasoline $$16,100,$

Maintenance $$2,900,$ Repairs $$4,000,$ Insurance $$3,800,$ and Advertising $$2,300.$

Cullumber has visited several financial institutions to discuss funding. The best interest rate he has been able to negotiate is

$15\%.$ Use this rate for cost of capital.

Cullumber expects each van to make $10$ round trips weekly and carry an average of $6$ students each trip. The service is

expected to operate $30$ weeks each year, and each student will be charged $$12$ for a round$-$trip ticket.
