• Supplies on hand at July 31, $275.
• The balance of the prepaid insurance account relates to the July 1 transaction at the end of Chapter 2.
• Depreciation of the office equipment is $50.
• The balance of the unearned revenue account relates to the contract between PS Music and KXMD, described in the July 3 transaction at the end of Chapter 2.
• Accrued wages as of July 31 were $140.

Instructions

   18 Accumulated Depreciation—Office Equipment

   22 Wages Payable

   57 Insurance Expense

   58 Depreciation Expense

2. 2. Post the adjusting entries, inserting balances in the accounts affected.
3. 3. Prepare an adjusted trial balance.

To determine

Adjusting entries:

Adjusting entries refers to the entries that are made at the end of an accounting period in accordance with revenue recognition principle, and expenses recognition principle.  All adjusting entries affect at least one income statement account (revenue or expense), and one balance sheet account (asset or liability).

Rules of Debit and Credit:

Following rules are followed for debiting and crediting different accounts while they occur in business transactions:

• Debit, all increase in assets, expenses and dividends, all decrease in liabilities, revenues and stockholders’ equities.
• Credit, all increase in liabilities, revenues, and stockholders’ equities, all decrease in assets, expenses.

T-account:

T-account refers to an individual account, where the increases or decreases in the value of specific asset, liability, stockholder’s equity, revenue, and expenditure items are recorded.

This account is referred to as the T-account, because the alignment of the components of the account resembles the capital letter ‘T’.’ An account consists of the three main components which are as follows:

1. (a) The title of the account
2. (b) The left or debit side
3. (c) The right or credit side

Adjusted trial balance:

Adjusted trial balance is a summary of all the ledger accounts, and it contains the balances of all the accounts after the adjustment entries are journalized, and posted.

To prepare: The adjusting entries in the books of Company PS at the end of the July 31, 2019.

Table (1)

Working notes:

1. Calculated the value of accrued fees during the July

$\begin{array}{c}\text{Fees earned=}\left(\begin{array}{l}\text{Total hours of music provided}-\\ \text{Music billed during the month}\end{array}\right)\times \text{Rate per hour}\\ \text{=}\left(\text{115 Hr}\text{.}-80\text{Hr}\text{.}\right)\times \$40\\ =35\text{ Hr}\text{.}\times \text{\$40}\\ \text{=\$1,400}\end{array}$ (1)

Hence, fees earned during the July are $1,400.

2. Calculate the value of supplies expense

$\begin{array}{c}\text{Supplies expense=}\left(\begin{array}{l}\text{The value of supplies at the beginning of the month}-\\ \text{Supplies on the hand at the end of the month}\end{array}\right)\\ =\$1,020-\$275\\ =\$745\end{array}$ (2)

Hence, supplies expense during the July is $745.

3. Calculate the value of insurance expense

$\begin{array}{c}\text{Insurance expense=}\frac{\text{The amount of one year premium}}{\text{No}\text{. of months in the year}}\\ =\frac{\$2,700}{12\text{ months}}\\ =\$225\end{array}$ (3)

Hence, insurance expense during the July is $745.

4. Calculate the value of unearned fees at the end of the July

$\begin{array}{c}\text{Unearned fees=}\frac{\text{Unearned fees at the beginning on the year}}{\text{2 months}}\\ =\frac{\$7,200}{2\text{ months}}\\ =\$3,600\end{array}$ (4)

Hence, unearned fees at the end of the July are $3,600.
