Hamburgers and Pizzas:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "h how many hamburgers, p how many pizzas.
\n" ); document.write( "\"h%2Bp=30\" and \"h%2Fp=5\";
\n" ); document.write( "Multiply the ratio equation by p and get \"h=5p\", and substitute this in the total count equation.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"5p%2Bp=30\"
\n" ); document.write( "\"6p=30\"
\n" ); document.write( "\"highlight%28p=5%29\" and then \"highlight%28h=25%29\"
\n" ); document.write( "
\n" );
