Salesperson must generate a sales of $ 26280 in order to earn $2,816.90 per month in total compensation
<em><u>Solution:</u></em>
Given that,
A salesperson is paid a base salary of $1700 per month plus a 4.25% commission on sales
Therefore,
Total salary = 1700 + 4.25 % commission on sales
<em><u>How much sales must he generate in order to earn $2,816.90 per month in total compensation?</u></em>
Therefore, let us first subtract the basic salary
2816.90 - 1700 = 1116.9
We have to find the sales he must generate
Let "x" be the sales he must generate
4.25 % of x = 1116.9
Therefore,

Thus he must generate a sales of $ 26280 in order to earn $2,816.90 per month in total compensation
