Final answer:
The impact on the accounting equation will be that assets will decrease by $100.
Step-by-step explanation:
The impact on the accounting equation will be that assets will decrease by $100.
In the accounting equation, assets = liabilities + owner's equity. When the company earns $100 of service revenue from a client, it increases both revenue (which is part of owner's equity) and accounts receivable (which is part of assets).
However, when only $30 is collected, it means that the company has reduced its accounts receivable by $30, resulting in a decrease in assets. The remaining $70 ($100 - $30) would still be recorded as accounts receivable.
