In part a) of Q6, please directly calculate the COGS of each sale using the unit cost information provided in brackets following the transaction description. In parts e) and f) of Q6, as required by the system, when calculating the total cost for each batch of inventory, please round to the nearest whole number. Exmaple: Ending inventory =0.371100+0.396100+0.416100=37.1+39.6+41.6 Then we should round each of 37,1,39.6,41.6 into 37,40,42 first. In this example, Ending inventory 37+40+42=119 (NOT 37.1+39.6+41.6=118.3=118!) On December 1, 2020, Vaughn Printers had the account balances shown below.
