1. A company wants to buy a machinery for $100,000. The company borrows one fourth of this amount from a bank at 15% annual interest. The loan will be repaid using equal annual payments over a 3-year period. The machinery will be used for 5 years and then sold for $5,000. The machinery will generate annual revenues of $30,000 each year over the five year ownership period. Find the rate of return of this investment. If the company uses a MARR 18% per year, is this investment worthwhile? (i*-16.25%)
