Kelly has a collection of nickels, dimes, and quarters with a total value of $6.10. There are four more nickels than dimes and twice as many quarters as nickels. How many of each coin is in her collection?
\n" ); document.write( "
Let the number of nickels be N
\n" );
document.write( "Then number of dimes = N - 4, and number of quarters: 2N
\n" );
document.write( "We then get: .05N + .1(N - 4) + .25(2N) = 6.1
\n" );
document.write( ".05N + .1N - .4 + .5N = 6.1
\n" );
document.write( ".65N = 6.1 + .4
\n" );
document.write( ".65N = 6.5
\n" );
document.write( "Number of nickels, or \"highlight_green%28matrix%281%2C5%2C+N%2C+%22=%22%2C+6.5%2F.65%2C+%22=%22%2C+10%29%29\"
\n" );
document.write( "You should now be able to find the number of dimes, and quarters. \n" );
