Madeline has total of 64 coins.
\n" ); document.write( "Number of coins:
\n" ); document.write( "x = number of Quaters
\n" ); document.write( "64-x = number of half dollars. \r
\n" ); document.write( "\n" ); document.write( "Value in cents:
\n" ); document.write( "25x = Number of cents in quarters
\n" ); document.write( "50(64-x) = number of cents in half dollars\r
\n" ); document.write( "\n" ); document.write( "Remember that everything has to be changed to cents. So $20.00 has to be changed to cents by multiplying with 100. $20.00 = 20 * 100 = 2000 cents.\r
\n" ); document.write( "\n" ); document.write( "\"25x%2B50%2864-x%29=2000\"
\n" ); document.write( "\"25x%2B3200%2B50x=2000\"
\n" ); document.write( "\"25x-50x=2000-3200\"
\n" ); document.write( "\"-50x=-1200\"
\n" ); document.write( "\"x=48\"
\n" ); document.write( "\"64-x=64-48=16\"\r
\n" ); document.write( "\n" ); document.write( "She has 48 Quarters and 16 Half-dollars.
\n" ); document.write( "
\n" );
