She estimates benefits of $20,000 in the first year, and benefits are increasing by 10% per year. (10pts) What is the payback period for the machine? (20pts) Suppose that the machine life is 15 years and machine has a salvage value of 20% of the initial cost at the end of its useful life. If the MARR of the company is 11% per year, is this investment acceptable? Why? Problem 2: (Exercise 6.4 is modified). A company would like to purchase a machine for $375,000 with a life of 10 years. They estimate the salvage value to be 6% of the initial machine cost. Other operating costs are estimated to be $32,500 per year. The interest rate the company uses to justify their investments, namely the MARR is 18% per year compounded yearly. (10pts) What is the capital recovery cost? (20pts) What is the minimum amount of annual revenue ($ per year?) that makes this investment an attractive option for the company? Problem 3: (Exercise 6.5 is modified). Initial Cost: ($300,000) The Study Period: 15 years Salvage (Market) Value of the Project: 12% of the initial cost Operating Costs in the first year: ($7,500) Operating costs increase by 5% per year Benefits in the first year: $30,000 Benefit increase by 13% per year MARR: 9% per year (30pts)Determine the NPW, AW, FW of the project. (10pts) is the Project acceptable? WHY? PLEASE UPLOAD YOUR EXCEL FILES
