Convert an amount to a discounted

[monkeybidz]

I have a variable: $price

 

$price = "100.00";

 

I need to get 50% of 100.00 when another variable value = Yes:

 

if($discount = 'Yes')

 

When it is = to Yes, i need $price to = $price - 50% discount.

 

Can anyone help? I have had this same question answered before, but cannot seem to find some of my post recently.

<?php

if (strtolower($discount) == "yes") {
    $discountPrice =($price \ .5);
    $newPrice = $price - $discountPrice;
}
?>
