x = original price
\n" ); document.write( "---
\n" ); document.write( "final sale price:
\n" ); document.write( "y = (0.70x)*1.20
\n" ); document.write( "y = 0.70*1.20x
\n" ); document.write( "y = 0.84x
\n" ); document.write( "---
\n" ); document.write( "final price as a percent of the original price:
\n" ); document.write( "(y/x) * 100
\n" ); document.write( "(0.84x/x) * 100
\n" ); document.write( "0.84 * 100
\n" ); document.write( "84%
