Adjusting Journal Entries:
1. Debit Supplies Expense $8,400
Credit Supplies $8,400
To adjust for supplies expenses for the year.
2. Debit Deferred Revenue $5,600
Credit Service Revenue $5,600
To adjust for services provided to customers.
3. Debit Salaries Expense $6,200
Credit Salaries Payable $6,200
To adjust for unpaid salaries at the end of the year.
4. Debit Interest Receivable $396
Credit Interest Revenue $396
To adjust for unreceived interest due for 9 months.
Explanation:
a) Data and Calculations:
Supplies = $13,500
Service revenue = $151,800 ($146,200 + 5,600)
Interest receivable = $396
Interest revenue = $396
Salaries payable = $6,200
Supplies expense = $8,400 ($13,500 - $5,100)
Deferred revenue = 2,500 ($8,100 - 5,600)
Salaries expense = 71,500 (65,300 + 6,200)
b) Interest Revenue is computed at 8% of $6,600 for 9 months only. This results to $396 ($6,600 * 8% * 9/12).
