Answer:
210
Explanation:
First, we keep $150 on the back of our minds(or our paper).
Second, we would assume that Rose's would've designed the flyer at $150, making us determine how much flyers they bought for the remaining $42.
($192 - $150 = $42)
Now that we know all of this, we can begin.
12 x 5 is 60, so 60 cents makes 1 dollar.
So for every dollar, they can make 5 flyers.
If we do 5 x 42, we'll get the answer of 210, which is the amount of flyers she bought!
