\n" ); document.write( "Juan has 16 coins all nickels and dimes this collection of coins is worth 1.15 how many nickels and dimes are there
\n" ); document.write( "

Let number of nickels be N
\n" );
document.write( "Then number of dimes = 16 - N
\n" );
document.write( "We then get: .05N + .1(16 - N) = 1.15
\n" );
document.write( ".05N + 1.6 - .1N = 1.15
\n" );
document.write( ".05N - .1N = 1.15 - 1.6
\n" );
document.write( "- .05N = - .45
\n" );
document.write( "N, or number of nickels =  = 
\n" );
document.write( "Number of dimes: 16 - 9 =  \n" );
document.write( "

\n" );
