Hello,
\n" ); document.write( "Let's have \"x\" represent the original price of the sweater.
\n" ); document.write( "So we can see that:
\n" ); document.write( "25% times the cost of the sweater is what is saved, right? Or rewritten as:
\n" ); document.write( ".25x but we want the cost after the savings so we'd write it like this:
\n" ); document.write( "x-.25x will be the expression needed.
\n" ); document.write( "To put this in reality let's say the sweater cost $90 and see if this expression works.
\n" ); document.write( "$90-.25(90) Do the calculation and it is:
\n" ); document.write( "90-22.50 = $67.50
\n" ); document.write( "OK, it works.
\n" ); document.write( "RJ
