Chapter 18, Problem 1QS

A company acquires equipment, which has an estimated useful life of 8 years and no salvage value, for $48,000 at the beginning of the accounting period. What is the adjusting entry for depreciation at the end of one month if the company uses the straight-line method of depreciation?

I need help solving this general accounting question with the proper methodology.

An item of equipment owned by Bruno Manufacturing cost $180,000 and had an estimated use of 90,000 hours. During the first 3 years, the equipment was used for 15,000, 19,000, and 12,000 hours. The equipment has an estimated life of 8 years and an estimated salvage value of $30,000. Required: Determine the depreciation for each of the 3 years using the units of production method.
