The balance sheet reports revenues and selling costs for a period of time.
a. true
b. false

I would say false, the sheet that reports the revenues and the costs is known as the income statement. the balance sheet is the sheet that would report all of the assets (such as the cash, accounts receivable, or others). The balance sheet will also report all the liabilities (including the accounts payable, notes payable and others). Lastly, the balance sheet will also report the equity or the capital account of the business. So in a nutshell, the balance sheet reports the assets, liabilities, and owner's equity.

It depends on what the venn diagram is over
