Let n be the number of nickels, and then d will be the number of dimes. Their values will then be 5n and 10d respectively...then we have
\n" ); document.write( "5n + 10d = 330 (thinking in cents now)
\n" ); document.write( "n + d = 42
\n" ); document.write( "If we multiply the bottom one by 5 and subtract,
\n" ); document.write( "5n + 10d = 330
\n" ); document.write( "-(5n + 5d = 210)
\n" ); document.write( "we get
\n" ); document.write( "5d = 120
\n" ); document.write( "d = 24 and
\n" ); document.write( "n = 18
\n" ); document.write( "Check to see they add to $3.30...
\n" ); document.write( "
\n" );
