I believe that it is 75%, because if you take 20*.50= 10*.50=5= 75% of your original price. I think..
Try to find what y is when x is equal to one.
48/16= 3
So, when x is 1, y is 3.
(1,3)
All you need to do is multiply 176 by 3 for the correct value of y.
176*3= 528
When x= 176, y= 528. (176,528)
I hope this helps!
