First find out what Martha actually paid for each item.
\n" ); document.write( "The $60 skirt was 40% off so to find out how much she paid
\n" ); document.write( "multiply 60 times .40
\n" ); document.write( "\"%2860%29%28.40%29=24\"
\n" ); document.write( "Marth saved $24 on the skirt
\n" ); document.write( "So the actual price paid is
\n" ); document.write( "$60-$24
\n" ); document.write( "So the skirt cost $36
\n" ); document.write( "Now the $40 blouse was 20% off
\n" ); document.write( "multiply 40 times .20
\n" ); document.write( "\"%2840%29%28.20%29=8\"
\n" ); document.write( "Martha saved $8 on the blouse
\n" ); document.write( "Actual price paid for the blouse is
\n" ); document.write( "$40-$8
\n" ); document.write( "The blouse cost $32
\n" ); document.write( "Ok now we can find what percentage discount she received on the total purchase.
\n" ); document.write( "The total price before discount is
\n" ); document.write( "$60+$40=$100
\n" ); document.write( "The total price with the discount is
\n" ); document.write( "$36+$32=$68
\n" ); document.write( "Ok so the percentage we are looking for is
\n" ); document.write( "$68 is what percent of $100
\n" ); document.write( "It should be easy to see that the answer is 68% but lets do the math.
\n" ); document.write( "Divide $68 by $100
\n" ); document.write( "\"68%2F100\"
\n" ); document.write( "\".68\"
\n" ); document.write( "now multiply by 100 to get percent
\n" ); document.write( "68%
\n" ); document.write( "
\n" );
