Let x be the original price of the item. Marking it up 20% is the same as adding 20% of the original price, so we have:
\n" ); document.write( " $\"x+%2B+0.20%2Ax+=+150\"$
\n" ); document.write( "Combining terms:
\n" ); document.write( " $\"1.20%2Ax+=+150\"$
\n" ); document.write( "Dividing both sides by 1.20:
\n" ); document.write( " $\"%281.20%2Ax%29%2F1.20+=+150%2F1.20\"$
\n" ); document.write( " $\"x+=+125\"$
\n" ); document.write( "The original price of the item was $125.
\n" ); document.write( " \n" ); document.write( "

\n" );
