\n" ); document.write( "A magazine costs $3.30. Jerry used a combination of nickels, dimes, and quarters

0.05N + 0.10D + 0.25Q = 3.30\r\n" );
document.write( "                    D = N - 14\r\n" );

document.write( "\r\n" );
document.write( "Substitute (N - 14) for D and (5) for Q in 0.05N + 0.10D + 0.25Q = 3.30\r\n" );

document.write( "0.05N + 0.10(N - 14) + 0.25(5) = 3.30\r\n" );
document.write( "   0.05N + 0.10N - 1.40 + 1.25 = 3.30\r\n" );
document.write( "                  0.15N - 0.15 = 3.30\r\n" );
