Answer: The salesperson would take home $1088.01 for the day
Explanation:
Let x represent the salesperson's total sales per day.
A salesperson earns $99 per day, plus a 9% sales commission. This means that in a day in which the salesperson makes a total sales of x dollars, the total amount that he would earn is
99 + 0.09x
Therefore, the function that expresses her earnings as a function of sales is
99 + 0.09x
if the total sales were $999, then the amount that the salesperson would take home for the day is
99 + 0.99 × 999
= $1088.01
