Answer:
The journal entry is as follows:
Cash A/c Dr. $12,400
Accumulated Depreciation - Equipment A/c Dr. $21,900
Loss on sale of equipment A/c Dr. $4,700
To Equipment $39,000
(To record the sale)
Working notes:
Accumulated Depreciation - Equipment:
= [(Cost of tractor - Residual value) ÷ Service life] × No. of years
= [(39,000 - 2,500) ÷ 5] × 3
= $21,900
