$x .= .5 * $b * ((($a + (.25 * ($f - 25))) + $d + $e) * (1 + $g));

Above is the code I finally came up with that generates the correct prices
for any combination that you may choose from the page
(https://www.webgraffix.com/postsearchlight/Classifieds2.php).  I have
tested it pretty thoroughly, but would welcome any scenarios where anyone
found a combination of options that did not work.

I have one question - How do I round off a value to say, 2 digits.  For
instance, if you choose the Commercial Liner, 1 Insertion and 1 Week to run,
as well as 50 words total with 2 italicized and All Caps, then the price is
$36.375.  How would I take the value of "x" and round it off so that I have
2 digits after the decimal point?

Thanks,
