Question 8 (Mandatory) (14 points) If the five year total of Net Income is $6550, what is the TOTAL rental revenue earned given the following scenario: Two friends contributed $6500 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 $1,000. They rented out the machine to a customer for four years. Annual cash operating costs for insurance, taxes, and other items totaled $600 annually. At the end of the fourth year, the owners sold the equipment for $2400, instead of the $1,000 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.)
