University car wash built a deluxe car wash across the street from campus. the new machines cost $237,000 including installation. the company estimates that the equipment will have a residual value of $28,500. university car wash also estimates it will use the machine for six years or about 12,500 total hours. actual use per year was as follows:

1. prepare a depreciation schedule for six years using the straight-line method. (do not round your intermediate calculations.)

2. prepare a depreciation schedule for six years using the double-declining-balance method. (do not round your intermediate calculations.)

3. prepare a depreciation schedule for six years using the activity-based method. (round your "depreciation rate" to 2 decimal places and use this amount in all subsequent calculations.)
