Explanation:
2-years of 4,896 AKA 24 months
months outstanding during the year: August 1st to December 31th: 5 months
4,896 x 5/24 = 1,020
purchases of advertising materials  801
materials on hand at year-end       <u> (266)  </u>
advertising expense                         535 
we must reverse the entry as the rent revenue wasn't accrued yet we have unearned revenue and at year-end we adjust for the earned protion which is 2 months: 1,650 x 2/3 = 1,100
as the inerest are accrued it means we aren't paying them at year-end
