Accrued salaries and wages on December 31, 2021, amounted to $4,300. The Interest Receivable account was also left unchanged during 2021. Accrued interest on investments amounts to $4,400 on December 31, 2021. The unexpired portions of the insurance policies totaled $66,000 as of December 31, 2021. $28,200 was received on January 1, 2021, for the rent of a building for both 2021 and 2022. The entire amount was credited to rent revenue. Depreciation on equipment for the year was erroneously recorded as $5,200 rather than the correct figure of $52,000. A further review of depreciation calculations of prior years revealed that equipment depreciation of $7,400 was not recorded. It was decided that this oversight should be corrected by a prior period adjustment. 6. 7. Assuming that the books have not been closed, what are the adjusting entries necessary at December 31, 2021?
