8. Rent per month is $575. Since the month ended, the advance payment was expired. Therefore, prepaid rent for the first month becomes credit, and rent expense is debit. Prepaid rent is an advance payment paid to the owner for using the store temporarily. Generally, rent has to be paid at the beginning of the month. Therefore, whenever the month ends, the advance payment becomes an expense for a company.

9. Supplies Expense calculations for the month of January:

Beginning supplies = $3,400

Add: Purchase = $3,800

Total supplies at hand = $7,200

Less: Ending supplies = $3,100

Total Supplies expense= $4,100

10. Unearned and service revenue calculation:

Unearned Revenue for the month of January = $4,000

Service provided by the company during the month = $3,425

Unearned Revenue at the end of the month = $ 575

Since the company provided services for which they took advance payment, the unearned revenue (a liability account), reduced. Therefore, unearned revenue is reversed to debit.

11. Salaries expense is an expense, therefore, it is a debit. Salaries payable is a liability, therefore, it is a credit entry. Salaries payable arises due to unpaid salaries for the employees. As there are no calculations regarding salaries expense, the amount of $5,590 is the debit for expenses (Salaries), and credit for liabilities (Salaries payable).

12. To close the revenue account, the account must be reversed. Closing entry is generally given for revenue and expense accounts. Therefore, all the revenues must be debit to income summary's credit to close the accounts. Total service revenues:

3. Provided service to the customer = $25,800

10. (ADD): Service provided to the customer who paid in advance = $ 3,425

Total: $(25,800 + 3,425) = 29,225.

13. Since the expense accounts deduct from income, therefore, income summary needs to be debit, and expense accounts need to be a credit to close the account. Therefore, all the expense accounts (Rent, salary, and supplies expenses) must be a credit to close them. Adding all the items, we can get the income summary balance.
