The break-even function allows you to study problems involving a profit, when a quantity of items, with a cost to manufacture
and a fixed price to develop and market, is sold at a given price. See Figure 1.
Break-even Example
The sale price of an item is 300.00, the cost is 250.00, and the fixed cost is 150,000.00. How many units would have to be
sold to make a profit of 10,000.00?
