A company is considering buying a machine that would give a net cost savings of 60,000 per year for 10 years. The cost of the machine is $325,000. The company's weighted average cost of capital is 12%. What is the difference between the IRR and the ARR? Assume there is no depreciation (therefore the initial cost and the average cost are the same number). Please enter your answer as a percentage to two decimals without the % sign.
