   If your teacher has the regular price as $300, then a sale price of $225 represents a discount of 25% from the regular price, not 15%.

   If $225 really is 15% off the regular price, then the regular pricce must be approximately $265. I got this by dividing $225 by 0.85 (225/0.85) then checked my work by multiplying my result by 0.85 to verify that I was able to get back to the sale price specified.

   Glasses: $225
   Regular Price: x

   glasses+ 0.15 of the regular price= regular price
   225+0.15x= x
   225=x-0.15x
   x=225/0.85
   x=264.705…

   The regular price of the glasses was about $265

   225——–.85
   x———–1

   x = 225/.85 = 264.71

   If the regular price is 300, 15% off is 0.15*300 = 45

   The sale price should be 300 – 45 = 255.

   Maybe the teacher worked with 255 instead of 225.

   Finger’s mistake!
