What is the balance of cash after 4 years for the following scenario: Two friends contributed $5000 each to form a new business. The owners used the amounts contributed to purchase a machine for $6,000 cash. They estimated that the useful life of the machine was four years and the salvage value was $1,500. They rented out the machine to a customer for an annual rental of $2050 a year for four years. Annual cash operating costs for insurance, taxes, and other items totaled $350 annually. At the end of the fourth year, the owners sold the equipment for $1900, instead of the $1,500 salvage value initially estimated. (Hint: Compute the total net income and the total cash flows other than cash flows with owners for the five-year period as a whole.)
