Hi there!
First, let's use a proportion to figure out the commission the salesperson makes.
WORK:
x/15486 = 3/100
100x = 46458
x = 464.58 (commission)
Next, we'll add together the commission and her salary.
WORK:
464.58 + 1200 = 1664.58
ANSWER:
$1664.58
Hope this helps!! :)
If there's anything else that I can help you with, please let me know!
