Get the average from multiple items
<p>Let's suppose I have a list like this</p>

<pre><code>[name1, number1], [name2, number2], [name3, number 3]
</code></pre>

<p>For example</p>

<pre><code>[John, 86], [Joe, 94], [bob, 45], [andy, 34]
</code></pre>

<p>I'm trying to print out everyone above number 80 and get the average. So in this case I want to output</p>

<pre><code>John Joe 90
</code></pre>

<p>What is the most simple structure I can use to do this?</p>
