You can put this solution on YOUR website!
say you want 250g of peanut butter, you could
\n" ); document.write( "buy one 250g jar of peanut butter for $6.50 or
\n" ); document.write( "you would have to buy three 100g jars of peanut butter at $3.10 per jar,
\n" ); document.write( "3 * $3.10 = $9.30
\n" ); document.write( "therefore, buying one jar at $6.50 saves you
\n" ); document.write( "$9.30 - $6.50 = $2.80
\n" ); document.write( "************************************************
\n" ); document.write( "we can calculate the price per gram of peanut butter for each jar type
\n" ); document.write( "1) $6.50 / 250 = $0.026
\n" ); document.write( "2) $3.10 / 100 = $0.031
\n" ); document.write( "therefore the $6.50 for a 250g jar is cheaper\r
\n" ); document.write( "\n" ); document.write( "
