First, fint the roots of the equation
1.
2. You can see that this equation has two different real roots. Note that you can make this statement without finding roots, only knowing the value of discriminant: since D=81>0, then the equation has two different real roots.
Using the profit concept, it is found that the break-even point is of 61.6 units.
- Profit is given by revenue subtracted by cost.
- The break-even point is when the revenue is the same as the cost, which means that the profit is zero.
In this problem:
- Variable cost per unit x of $217, fixed cost of $5,420, thus, the cost equation is given by:
Selling price per unit of $305, thus, the revenue equation is given by:
The break-even point is the <u>value of x</u> for which:
Then
The break-even point is of 61.6 units.
