Q1) 2.2 : A company that makes self-clinching fasteners expects to purchase new production-line equipment in 5 years. If the new units will cost $450,000, how much should the company set aside each year, if the account earns 10% per year? Q2) 2 27 Rolled ball screws are suitable for high-precision applications such as water jet cutting. Their total manufacturing cost is expected to decrease because of increased productivity, as shown in the table. Determine the equivalent annual cost at an interest rate of 10% per year.
