&& operator for double
<p>I need abit of help with an if statement and operators. How could I do this:</p>

<pre><code>double AgePenalty = 0;
if (AgeOfCustomer &lt;= 21)
{
    AgePenalty = 15;
}
if (AgeOfCustomer &lt;= 30 &amp;&amp; AgeOfCustomer =&gt; 21) // cant use &amp;&amp; operator with double
{
    AgePenalty = 10;
}
</code></pre>

<p>This just says if the customer is younger than 21 apply a certain price tag; if the customer is between the ages of 21 and 25 apply smaller price tag etc. </p>
