Answer:
$400
Step-by-step explanation:
You first need to find how much you make on your commissions. As you earn 5% on your total sales, you would multiply the total sales by the percentage;
$4,500 x 5% = $225
This is how much you earn in commissions for the month. To find the total you are paid, add this amount to your salary;
$225 + $175 = $400
