Answer:
The $21,122 would he have to sell in a month if he wants to have a monthly income of $2400
Step-by-step explanation:
In this question we assume the value which is shown below
Let us assume the amount which is sell be X
So, the equation would be
Commission × (Sale amount - sales amount) + Base salary = Monthly income
0.09 × (X - $1,950) + $675 = $2,400
0.09X - $176 + $675 = $2,400
0.09X = $2,400 + $176 - $675
0.09X = $1,901
So, X = $21,122.22
X = Sale amount = $21,122.22
