Peters Ltd Has a Machine That Originally Cost $20 000

Peters Ltd has a machine that originally cost $20 000 and has accumulated depreciation of $5000.Its remaining life is assessed to be 5 years with no salvage value.The directors of Peters Ltd decide on 1 July 2003 to revalue the machine.They are unable to find market information on a machine in a similar state to theirs,so the market value of a new machine of the same type,$30 000,is used as a basis.What is/are the appropriate journal entry(ies) using the gross method to record the revaluation?
