title: Limit this query to only show to 2 decimal places
body: <p>I need to change my query to return only 2 decimal points</p>
  
  <pre><code>SELECT (AVG(cost)) AS 'Average Cost $'
  FROM donuts
  WHERE cost;
  </code></pre>
  
  <p>I don't want to use the ROUND function because I wont get a decimal.</p>
  
  <pre><code>SELECT ROUND(AVG(cost)) AS 'Average Cost $'
  FROM donuts
  WHERE cost;
  </code></pre>
  
  <p>Any Suggestions, </p>
