Answer:
$68,800
Step-by-step explanation:
Generally, under the General Depreciation System (GDS) MACRS we use the half-year convention and the depreciation rates are:
year depreciation %
1 20%
2 32%
3 19.20%
4 11.52%
5 11.52%
6 5.76%
When using MACRS, you do not consider any salvage value.
Depreciation expense 2020 = $344,000 x 20% = $68,800
The mid-quarter convention can be used only if 40% of total depreciable assets were purchased during the last 3 months of the year, but not when you purchase them during the first months.
