Explanation:
You need to analize the information provided:
- The comission on each sale made by the salesman is 18.14%.
- On a particular sale the salesman makes a comission of $152.39.
Then, the amount of the sale represents the 100%
Let be "x" the amount of that particular sale. You can use this procedure to calculate it:
![x=((\$152.39)(100\%))/(18.14\%)\\\\x=\$840.08](https://img.qammunity.org/2020/formulas/mathematics/middle-school/zt79o1hrfzqp3ksyh8b2sjrecafabul64e.png)
