UPDATE: We replaced the old GMAT Tuesday in this post with a new video because one of our readers spotted an error and brought it up to us–thank you, Alex!
This week is a continuation of last week’s GMAT Tuesday video! I’ll show you how to solve that tricky percent change problem faster with a little help from multipliers.
Leave me a comment or question below! It’d really make my day :).

After seeing this comment in particular, the concept became so much simpler, not that it wasn’t simple before.
Really, thankyou. 🙂
Difference of Squares, heh.
Wonderful 🙂
