Adding two price variables PHP
<p>I have variables...</p>

<pre><code>$price  (value 53.11)
$discount  (value 4.78)
</code></pre>

<p>if I add these variables like this...</p>

<pre><code>$beforeDiscount = ($price + $discount); 
</code></pre>

<p>I get <code>57.00</code> when I echo it</p>

<p>I want to get <code>57.89</code> but can't seem to make that happen.  How do I echo the true sum of these two variables?</p>
