I need to make Statement of Comprehensive Income and a Balance Sheet. But I have no idea which step before preparing it. Also, don't understand how the numbers adding up. Thank you

Assume that the ATB also shows normal balances for interest expense and interest payable of $300 each, that the balance for Cash was ?12,400, and that there was a balance for Loan Payable of ?2,000.The loan is non-current. Make sure your financial statements are in the format and form required in this course.(Hints:1) do not forget about EBIT, and 2) in the equity section of the Balance Sheet, show the ending balance of Retained Earnings, i.e., after the $3,000 balance has been updated as at 31 August 2020.)
