You can put this solution on YOUR website!
Let p=original price. If you buy a product that's 20% off, you're buying it with 20 percent of that price subtracted from that price. For instance, if an item is originally priced at $100 and it has a 10% discount you pay 10% less than $100. Or in other words 100-10%(100)=100-.1(100=100-10=90. So you would pay $90 instead of $100. The same idea applies here, but we don't know the original price, so we let that be our unknown.
\n" ); document.write( " $\"180=p-.2p\"$ Subtract like terms
\n" ); document.write( " $\"180=.8p\"$ Divide both sides by .8
\n" ); document.write( " $\"180%2F.8=p\"$
\n" ); document.write( " $\"p=225\"$
\n" ); document.write( "So the original price was $225
\n" ); document.write( "

\n" ); document.write( "Check:
\n" ); document.write( "$225-20% of 225=225-.2(225)=225-45=180 So our answer checks out. \n" ); document.write( "

\n" );
