Acme has branched out to rentals of office furniture to start-up companies. Consider a $5,000 desk. Desks last for six years and can be depreciated immediately. Assume that lease rates for old and new desks are the same and that Acmes pretax administrative costs are $400 per desk at the beginning of each year. The cost of capital is 9% and the tax rate is 21%. Lease payments are made in advance, that is, at the start of each year. The inflation rate is zero. Suppose a blue-chip company requests a six-year financial lease for a $5,000 desk. The company has just issued five-year notes at an interest rate of 6% per year.

What is the break-even rate in this case? (Do not round intermediate calculations. Round your answer to 2 decimal places.)
