\n" );
document.write( "Let the number of quarters be Q
\n" );
document.write( "Then the number of nickels is: Q + 2
\n" );
document.write( "As each quarter is worth $0.25, and each nickel is worth $0.05, we can say that:
\n" );
document.write( ".25(Q) + .05(Q + 2) = 3.4
\n" );
document.write( ".25Q + .05Q + .1 = 3.4
\n" );
document.write( ".25Q + .05Q = 3.4 - .1
\n" );
document.write( ".3Q = 3.3
\n" );
document.write( "Q, or the number of quarters = , or 
\n" );
document.write( "Number of nickels: 11 + 2, or

\n" );
document.write( "Quarters: 11, for a quarter-amount of 11(.25), or $2.75
\n" );
document.write( "Nickels:   13, for a nickel-amount of 13(.05), or   $0.65
\n" );
document.write( "Total:      24  coins,     for a total amount of        $3.40
\n" );
document.write( "As seen also, there are 2 more nickels than quarters (13 nickels to 11 quarters) \n" );
