\r\n" );
document.write( "\r\n" );
document.write( "Let d be the number of dimes.\r\n" );
document.write( "\r\n" );
document.write( "Then the number of quarters is (58-d), according to the condition.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Then we can write the money equation for the total in the form\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    10d + 25*(58-d) = 985   cents.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From the equation,  d =  = 31.\r\n" );
document.write( "\r\n" );
document.write( "ANSWER.  31 dimes and 58-31 = 27 quarters.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "CHECK.   31*10 + 27*25 = 985 cents.    ! Precisely correct !\r\n" );
