\n" ); document.write( "

Let number of .45 stamps purchased be F
\n" );
document.write( "Then number of 65c stamps purchased = 50 - F
\n" );
document.write( "We then get: .45F + .65(50 - F) = 24.5
\n" );
document.write( ".45F + 32.5 - .65F = 24.5
\n" );
document.write( ".45F - .65F = 24.5 - 32.5
\n" );
document.write( "- .2F = - 8
\n" );
document.write( "F, or number of 45c stamps purchased = , or
