If $60,000.00 is the total sales from selling toaster ovens at $16.00 each, then the total units of toaster ovens sold would be 3,750.00 units. If expenses where given, say for example, 40% of the sales, with a profit before tax of $60,000.00, then total sales should be $84,000.00 equivalent to 5,250 units of toaster ovens.
