\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~\r

\n" ); document.write( "\n" ); document.write( "

\r\n" );
document.write( "Let \"n\" be the number of nickels in the collection.\r\n" );
document.write( "Then the number of dimes is (41-n).\r\n" );
document.write( "\r\n" );
document.write( "Nickels contribute 5n       cents into the total.\r\n" );
document.write( "Dimes   contribute 10(41-n) cents into the total.\r\n" );
document.write( "\r\n" );
document.write( "The total is 5n + 10(41-n) cents.\r\n" );
document.write( "\r\n" );
document.write( "From the other side. the total is 275 cents, according to the condition.\r\n" );
document.write( "\r\n" );
document.write( "Hence,\r\n" );
document.write( "\r\n" );
document.write( "5n + 10(41-n) = 275.\r\n" );
document.write( "\r\n" );
document.write( "It is your equation to solve for \"n\". Simplify it:\r\n" );
document.write( "\r\n" );
document.write( "5n + 410 - 10n = 275,\r\n" );
document.write( "\r\n" );
document.write( "-5n = 275 - 410,\r\n" );
document.write( "\r\n" );
document.write( "-5n = -135,\r\n" );
document.write( "\r\n" );
document.write( "n =  = 27.\r\n" );
document.write( "\r\n" );
document.write( "Answer.  The number of nickels in the collection is 27.\r\n" );
document.write( "\r\n" );
document.write( "Check.   Then the number of dimes is 41-27 = 14.\r\n" );
document.write( "\r\n" );
document.write( "         27*5 + 14*10 = 275.  OK, correct !\r\n" );
