Ok, I know I have something wrong here but I cannot seem to figure it out? Any help is greatly appreciated...this is for my acctg I homework. Thanks!

How do you KNOW you have something wrong?

A quick look shows your Adjusted Trial Balance does indeed balance.

Do you have a final number you have to get that you are not getting?

The answer is supposed to be Net Income $15,000, I can only assume that I have added or subtracted something in the wrong place? BUT, everything you see on that page is what I have to go off of...so I am not sure what it could be because the Dr's and Cr's dont equal and they should right, on the balance sheet?

Some mistakes I have found in your JE:

E) Accrued Interest expense 200
JE should be:
Dr. Interest Expense 200
Cr. Interest Payable 200

F)
You reversed the journal entry.

It should be:
Dr. Unearned Service Revenue 4,400
Cr. Service Revenue 4,400

G)
You reversed the JE again.

You should:
Dr. Advertising Expense 100
Cr. AP 100

H)
The JE should be:
Dr. Interest Receivable 200
Cr. Interest Revenue 200

Thank you, Thank You, I have done and redone that so many times it was all beginning to look alike to me lol

you're welcome
