Let n represent nickels. Then dimes are n+30; and quarters are 2n+60. So:
\n" ); document.write( "5n+10(n+30)+25(2n+60)=5050
\n" ); document.write( "65n+1800=5050
\n" ); document.write( "65n=3250
\n" ); document.write( "n=50
\n" ); document.write( "She has 50 nickels, 80 dimes, and 160 quarters. ☺☺☺☺
\n" ); document.write( "
\n" );
