I need to answer this problem:

Tom's Grocery purchased 5 new cash registers for their new store and they paid $2,400 each for a total of $12,000 on August 1, 2013, the day they were delivered. The cash registers are expected to have useful lives of 5 years and they are not expected to have any salvage value. Tom's Grocery uses straight-line depreciation. The cash registers were recorded as long-lived assets at the time of the purchase and now Tom's needs to make an entry showing the expense related to these cash registers up to December 31, 2013.

I have to define what to put in asset, liability and equity and express with their respective T Account
