R Gilmour & Associates purchased and installed on credit a computer system that was commissioned on 1 April 2021 for

$66 000 ($60 000 + $6000 GST). It is expected that the computer system has a useful life of four years and residual value of $6600 ($6000+ $600 GST). Gilmour uses the straight line depreciation method and the business closes its accounts on 30 June.

After a time, the system proved inadequate and was sold for $16 500 ($15 000 + $1500 GST) cash on 1 October 2023.

A new system, purchased on credit, was installed and operational on 1 October 2023. It cost $82 500 ($75 000 + $7500 GST), is to be depreciated at 33.33% p.a. using the straight line method and there is an estimated residual value of $3300

($3000 + $300).
