Final answer:
The annual depreciation expense for the equipment is $3,600.
Step-by-step explanation:
To calculate the annual depreciation expense for the equipment, we need to determine the depreciation per year. We can use the straight-line depreciation method, which divides the initial cost minus the salvage value by the useful life of the equipment. In this case, the initial cost is $20,000 and the salvage value is $2,000. The useful life is 5 years. So, the annual depreciation expense is:
(Initial Cost - Salvage Value) / Useful Life
($20,000 - $2,000) / 5 = $3,600
Therefore, the annual depreciation expense for the equipment is $3,600.
