Therefore, the dollar amount of sales required to obtain an income of $15,100 is:
![15,100 = Sales - FC - VC\\0.5*Sales = Sales -VC\\15,100 = 0.5*Sales - 84,000\\Sales = \$198,200](https://img.qammunity.org/2021/formulas/business/college/oyw79c8na9kokqvbid13rzrsu8y0277f1u.png)
The dollar amount of sales must be $198,200
