Ed's year end is 30 September. He depreciates office furniture at 15% per annum on the straight line basis. A full year's depreciation is charged in the year an asset is purchased, and no depreciation is charged in the year it is sold. In March 2005 Ed bought office furniture for $80,000. If he sells the office furniture for $39,000 in July 2008, what will be Ed's profit or loss on disposal?
