You added 2 to the 5 when you only carried one.

Not to imagine I could hold a candle to you; I wonder, are all of the X's necessary. "Let x be the highest market price."
later, "1x -.25x = .75x = sale pricex."
1x = $66.64
-25% = -$16.66
1x -.25x = $49.98 = sale price.
with a 2 cent remainder.
Your still the best. -.25x = $49.98

hey Sal just quickly wanted to say that I think you messed up by saying that 125x5=725 when it is 625 therefore you got 94.75. I just got 93.75. not a big deal just wanted to clarify that and awesome video. thanks a lot!

So to put this in simple terms (no offence Sal) the key to this question is the "25% OFF" so the marked price is going to represent 75%(because 100-25=75) of the original price,so you do 0.75 divided into how ever much money you have.Thank you Sal,very good lesson.
