Answer 1

You had several errors in your code.

Here is a functional example:

var button = document.getElementById("calculate");
button.addEventListener('click', CalcTip);

function CalcTip(){
  var bill = document.getElementById('bill');
  var people = document.getElementById('people');  
  var total = parseInt(bill.value) / parseInt(people.value);                 
  total = Math.round(total * 100) / 100;
  
  document.getElementById("last").innerHTML = "$" + total;
}

<button type="button" id="calculate">Calc Tip</button><br>

<input type="text" id="bill"><br>
<input type="text" id="people">this can't be 0<br>

<div id="last"></div>
