title: Calculate IEnumerable<decimal> with decimal without using for-loop
body: <p>I was given a discount percentage as a decimal and I have <code>IEnumerable&lt;decimal&gt;</code> as a list of prices. I want to calculate discount price for each one in linq.</p>
  
  <pre><code>IEnumerable&lt;decimal&gt; prices = new IEnumerable&lt;decimal&gt;() { 100, 200, 300};
  decimal discountPercentage = 20;
  </code></pre>
  
  <p>Shoot me some idea, I would love to try anything.</p>
