Answer:
The difference in sales is that Hillary sold $2,400 more than Jon
Explanation:
To find each of their sales, start by dividing the amount they made by the percentage of commission that they earn.
Hillary
3498/.22 = 15,900
Jon
3780/.28 = 13,500
So now to find the difference, we subtract Jon's total from Hillary's.
15,900 - 13,500 = 2,400
