$12120 is the annual amortization expense
<u>Explanation:</u>
The following formula is used to calculate the annual depreciation expense that will be recorded in the books of accounts
Depreciation = ( cost of the asset minus salvage value) divide by number of years.
Given data in the question: number of years = 10, cost of the asset = $124000, salvage value = $28000
Putting the figures in the formula,
Depreciation expense = ($124000 minus $28000) divide by 10
After solving, we get = $12120
Thus, annual depreciation expense = $12120
