To determine

Determine the total revenue for the month of August.

Explanation of Solution

Revenue is known as “Top line” because it appears very top on the income statement of the company. It is used to imply profits or net income (bottom line) of the company by subtracting the total expenses from total revenues.

Determine the total revenue for the month of August:

$\begin{array}{c}\text{Total revenue for the month of August = }\left(\begin{array}{l}\text{Service revenue +}\\ \text{ Revenue earned on account }\\ \text{+ Service fees}\end{array}\right)\\ \text{= }\left(\text{\$3,000 +\$4,000 + \$2,800}\right)\\ =\$9,800\end{array}$

Conclusion

Hence, the total revenue for the month of August is $9,800.

To determine

Determine the total expenses for the month of August.

Explanation of Solution

Expense is the cost borne by a company to produce and sell the goods and services to the customers. This involves outflow of cash by making a payment for an individual or company for a particular item and service.

Determine the total expenses for the month of August:

$\begin{array}{c}\text{Total expenses for the month of August = }\left(\begin{array}{l}\text{Rent expense +}\\ \text{ Wages expense + }\\ \text{Phone expense +}\\ \text{Advertising expense}\end{array}\right)\\ \text{= }\left(\begin{array}{l}\text{\$700 + \$500 +}\\ \text{ \$100 + \$2,000}\end{array}\right)\\ =\$3,300\end{array}$

Conclusion

Hence, the total expense for the month of August is $3,300.

To determine

Determine the net income for the month of August.

Explanation of Solution

Net income: The bottom line of income statement which is the result of excess of earnings from operations (revenues) over the costs incurred for earning revenues (expenses) is referred to as net income.

Determine the net income for the month of August:

$\begin{array}{c}\text{Net income for the month of August = }\left(\begin{array}{l}\text{Total revenues}\\ -\text{Total expenses}\end{array}\right)\\ \text{= }\left(\text{\$9,800}-\$3,300\right)\\ =\$6,500\end{array}$

Conclusion

Hence, the net income for the month of August is $6,500.

To determine

Determine the amount of ending owner’s equity.

To determine

Show the accounting equation for the end of month.

Explanation of Solution

Accounting equation: Accounting equation is an accounting tool expressed in the form of equation, by creating a relation between resources or assets of a company and claims of resources to creditors and owners. Accounting equation is expressed as shown below:

$\begin{array}{c}\text{Assets = Liabilities + Owners' Equity}\\ \text{Assets = Liabilities+}\left\{\left(\begin{array}{l}\text{Owners' }\\ \text{investments}\end{array}\right)\text{+}\left(\begin{array}{l}\text{Owners' }\\ \text{withdrawals}\end{array}\right)\text{+}\left(\begin{array}{l}\left(\text{Revenues}\right)\text{–}\\ \left(\text{Expenses}\right)\end{array}\right)\right\}\end{array}$

Show the accounting equation for the end of month:

$\begin{array}{l}\text{Assets = Liabilities + Owner's Equity}\\ \text{\$38,000 = \$4,500 +\$33,500}\end{array}$

Working note:

Calculate the amount of assets:

$\begin{array}{c}\text{Assets = }\left(\begin{array}{l}\text{Cash + Accounts receivable + Office supplies}\\ \text{ + Prepaid insurance + Plumbing equipment + Van}\end{array}\right)\\ =\left(\begin{array}{l}\$20,200+\$2,700+\$300\\ +\$800+\$6,000+\$8,000\end{array}\right)\\ =\$38,000\end{array}$
