n = 3d
\n" ); document.write( "0.05n+0.10d = 25 substitute for n
\n" ); document.write( "0.05(3d)+0.10d = 25
\n" ); document.write( "0.15d+0.10d = 25
\n" ); document.write( "0.25d = 25
\n" ); document.write( "d = 100
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
\n" ); document.write( "n/3 = d
\n" ); document.write( "0.05n+0.10d = 25 substitute for d:
\n" ); document.write( "0.05n+0.10(n/3) = 25
\n" ); document.write( "0.15n+0.10n = 75
\n" ); document.write( "0.25n = 75
\n" ); document.write( "n = 300
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
\n" ); document.write( "Check:
\n" ); document.write( "d = 100*0.10 = 10
\n" ); document.write( "n = 300*0.05 = 15
\n" ); document.write( "___________---------
\n" ); document.write( "Total. . . . . 25 We have the correct answer
\n" ); document.write( "
\n" );
