As the aircraft was out of service for some weeks due to the accident, Flightline took the opportunity to upgrade its cabin facilities at a cost of $4.5 million. This did not increase the estimated remaining life of the cabin fittings, but the improved facilities enabled Flightline to substantially increase the air fares on this aircraft.
What is the carrying amount of the cabin fittings as at 31 March 20X9?
I understood how to do it and the Carrying value is 12000 (7500+4500) but why do we have to find the depreciation for that *6/18 if only carrying amount is asked
