x = retail price
\n" ); document.write( ".2*x = discount off retail price\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( ".2x = 45
\n" ); document.write( "divide both sides of equation by .2
\n" ); document.write( "x = 45/.2 = 225.00\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Retail Price was $225.00
\n" ); document.write( ".2 * $225.00 = $45.00 = discount.
\n" ); document.write( "Discount Price = Retail Price minus Discount = $225.00 - $45.00 = $180.00\r
