\n" ); document.write( "Katie has a collection of nickels, dimes and quarters with a total value of $3.75. There are 6 more dimes than nickels and 3 more quarters than nickels, how many of each coin does she have?
\n" ); document.write( "

 
\n" );
document.write( "Let number of nickels be N
\n" );
document.write( "Then number of dimes = N + 6, and number of quarters = N + 3
\n" );
document.write( "We then have: .05(N) + .1(N + 6) + .25(N + 3) = 3.75
\n" );
document.write( ".05N + .1N + .6 + .25N + .75 = 3.75
\n" );
document.write( ".05N + .1N + .25N + .6 + .75 = 3.75
\n" );
document.write( ".4N + 1.35 = 3.75
\n" );
document.write( ".4N = 3.75 - 1.35
\n" );
document.write( ".4N = 2.4
\n" );
document.write( "N, or number of nickels = , or . 
\n" );
document.write( "From this, I would think that you should be able to determine the number of dimes and quarters.
