Step-by-step explanation
The break-even point is the point where the profit and the loss are the same (equal). To calculate it, we have the following formula:
![Break-even=\frac{Fixed\text{ costs}}{Price-Variable\text{ costs}}](https://img.qammunity.org/2023/formulas/mathematics/high-school/p4072vct3yyp44t8jrxe88vjxzgombe5on.png)
where "Price" denotes the value estimate (per unit) by the company. In this case, such a value is $50. And "Variable costs" denotes the variable cost per table; in this case, it's $22. Then,
![\text{Break}-\text{even}=(13000)/(50-22)=(13000)/(28)\approx464.2](https://img.qammunity.org/2023/formulas/mathematics/high-school/12671jkerpsrzpg3ipkd9ar21wplvxqsk3.png)
Now, note that the obtained number of sales is not an entire number. In such cases, we choose the next integer (for we prefer no loss); in this particular case, it's 465.
Answer
The total sales the company needs to break even are 465.
