Answer: her commission would be $3780
Explanation:
The Real estate agent receives a commission of 9% on property sold through her. If she made a sale of $x, her commission would be
9/100 × x = 0.09×x = 0.09x
Since she made a sale of $42,000, x becomes $42,000. Therefore
her commission would be
9/100× 42000 = 0.09× 42000 = $3780
