Acme has branched out to rentals of office furniture to start-up companies. Consider a $3,200 desk. Desks last for six years and can be depreciated on a five-year MACRS schedule. Assume that lease rates for old and new desks are the same and that Acmes pretax administrative costs are $440 per desk at the beginning of each year. The cost of capital is 11% and the tax rate is 35%. Lease payments are made in advance, that is, at the start of each year. The inflation rate is zero.

can you solve this using an excel spreadsheet please, so I can see where the numbers come from, please?
