You can put this solution on YOUR website! A dress boutique was trying to sell a formal dress that no one seemed to want. The dress was first marked down by 20% off the original price, but no one bought it. Next, it was marked down 25% more off the first sale price, but still no one would buy it. Finally, it was offered for 30% off the second sale price, and someone purchased it for $63. What was the original price of the dress
---------------
$63 is 70% of the price before the 30% off, P1
--> P1*0.7 = $63
P1 = $90
-------
$90 is 75% of the price before the 25% off, P2
P2*0.75 = $90
P2 = $120
----------
$120 is 80% of the price before the 20% off, P3
P3*0.8 = $120
P3 = $150 = the original price
-----------
$150 - 20% = $120
$120 - 25% = $90
$90 - 30% = $63
