\r\n" );
document.write( "Let \"n\" be the number of nickels.\r\n" );
document.write( "\r\n" );
document.write( "Then the number of quarters is (22-n).\r\n" );
document.write( "\r\n" );
document.write( "The nickels  contribute 5n cents to the total.\r\n" );
document.write( "The quarters contribute 25*(22-n) cents to the total.\r\n" );
document.write( "\r\n" );
document.write( "The \"value\" equation is\r\n" );
document.write( "\r\n" );
document.write( "5n + 25*(22-n) = 250 cents.\r\n" );
document.write( "\r\n" );
document.write( "Simplify and solve for \"n\":\r\n" );
document.write( "\r\n" );
document.write( "5n + 550 - 25n = 250,\r\n" );
document.write( "\r\n" );
document.write( "-20n = 250 - 550,\r\n" );
document.write( "\r\n" );
document.write( "-20n = - 300  --->  n =  = 15.\r\n" );
document.write( "\r\n" );
document.write( "Answer. 15 nickels and 22 - 15 = 7 quarters.\r\n" );
