Use the following information for problems 4, 5, 6, and 7 A project initially costs $40,000 and has a 10 year lifetime. The project returns benefits of $10,000 at the end of the first year, increasing by 12% in each of the following years. Costs are incurred at a rate of $4.000 per year. The anticipated salvage value is $7,000. MARR - 15%. 4.
