I can't seem to figure out how to do ammortization..
And for the sales.. I basically added the initial sales to the sales that were unearned before but now are earned.
It would be very helpful , thanks!

Sales?

You had 4,000 in unearned sales

You are told that “Unearned sales revenue of $1,175 is still unearned at December 31. On the sales that were earned, the cost of goods sold was $2,200.”

Therefore, add 2,825 to the Sales amount.
Plus, add 2,200 to the COGS amount.
