Let D = no of Dimes, and N = no of Nickels
\n" ); document.write( ".
\n" ); document.write( "1) .1 D + .05 N = 5.65
\n" ); document.write( ".
\n" ); document.write( "2) .1(2D) +.05( N+8) = 10.45
\n" ); document.write( ".
\n" ); document.write( "or .2D +.05N +.40 =10.45
\n" ); document.write( ".
\n" ); document.write( "or .2D +.05N = 10.05
\n" ); document.write( ".
\n" ); document.write( "substract 2) - 1)
\n" ); document.write( ".
\n" ); document.write( ".1D = 4.40
\n" ); document.write( ".
\n" ); document.write( "D = 44
\n" ); document.write( ".
\n" ); document.write( "Subst in 1) .1(44) + .05 N = 5.65
\n" ); document.write( ".
\n" ); document.write( "4.4 + .05 N = 5.65
\n" ); document.write( ".
\n" ); document.write( ".05 N = 1.25
\n" ); document.write( ".
\n" ); document.write( "N = 25
\n" ); document.write( ".
\n" ); document.write( "check,,1) .1(44) + .05(25) = 5.65,,,,ok
\n" ); document.write( "2) .1(88) + .05(33) = 10.45,,, ok \n" ); document.write( "
\n" );
