I have the following information

FIFO (COGD 3300; Ending Inventory 3140)

LIFO (COGS 4600; Ending Inventory 1840)

Weighted Average (COGS 3990; Ending Inventory 2447)

I am given the net income using the weighted average cost follow assumption of 13, 900

I need assistance determining what the net income of FIFO and LIFO would be and round the unit cost to 2 decimal places. I would like a solution and step by step instructions,.

Thanks
