<?php


$item1 = floatval($_POST['item1']);
$item2 = floatval($_POST['item2']);
$item3 = floatval($_POST['item3']);
$item4 = floatval($_POST['item4']);
$item5 = floatval($_POST['item5']);

$tax = ".10"; // 10%

if (isset($_POST['submit']))
{

$subtotal = $item1+$item2+$item3+$item4+$item5;
$taxAmount = $subtotal * $tax;
$total = $subtotal+$taxAmount;

echo "Subtotal: $subtotal<br>
  Tax: $taxAmount<br>
  Total: $total";
  
}

Thank you so much for you're help you are awesome.  The teacher did give some examples but the editor that i am using isn't showing color so I can't tell if what I am typing is correct or not.  This is my first class and I am sooooo green when it come to writing code.

P.S.  Sorry for posting in the wrong spot this is my first time in this forum.
