$180

Step-by-step explanation:

If Fiona earned 15% commision on what she sold, that means that we have to make a proportion to see how much she made.

15/100=x/1200

This is because 15/100 is the same as 15%. An easier way of doing this is just multiplying 0.15x1200 because that's basically how much she earned.

But, if we solve the proportion 15/100=x/1200, we get:

100x=18,000

Now, we divide each side by 100 to find x. Thus,

100x/100=18,000/100.

And,

x=180.
