2.
Cash $11200 Dr
Accumulated depreciation-Equipment $20400 Dr
Loss on Disposal $4400 Dr
Equipment Account-Tractor $36000 Cr
Step-by-step explanation:
a.
The straight line method of depreciation charges equal or constant amount of depreciation expense through out the useful life of an asset. The formula for depreciation expense per year under straight line method is,
Depreciation expense per year = (Cost - Residual value) / estimated useful life
Depreciation expense per year = (36000 - 2000) / 5 = $6800
The accumulated depreciation after three years = 6800 *3 = $20400
After three years, the tractor had a Carrying value of = 36000 - 20400 = $15600
Thus, there is a gain on disposal of = 18000 - 15600 = 2400
b.
If the cash received from sale or disposal was $11200. Then there will be a loss on disposal as carrying value is greater than the cash received.
The loss on disposal = 11200 - 15600 = 4400 loss
