d. $6,000 gain on disposal.
Explanation: Proceeds minus book value results in a gain if proceeds exceed book
value. Here, $66,000 is the proceeds.
The book value is Cost – Accumulated Depreciation. Determine accumulated
depreciation as of July 1, 2019. We are given the Accumulated Depreciation
balance at January 1, 2019, so we need to add another six months of depreciation
for the period from January through June 2019.
Annual Depreciation Expense =
(Cost $180,000 – Salvage Value $30,000)/useful life 5 yrs = $30,000/year
Depreciation Expense.
We only need to add ½ year of depreciation to the January 1, 2019, balance so
add $15,000 (1/2 of $30,000) to $105,000 for an Accumulated Depreciation
balance of $120,000 at July 1, 2019. Now, proceeds $66,000 – Book Value
($180,000-$120,000) = $6,000 gain
