Question : Php: need help

Hello. Once again having problems with hometask. My home task is the following:

Print out a receipt for a restaurant meal (must contain the following)
1.      String variables for each course: Pasta Di Pina, pepsi, cake, entrée. Each course variable should contain the customer's menu choice (ie. "hotdog").
2.      float or integer variable in dollars for each course price.
3.      A float variable for the 8% sales tax, and another one for the customer's 15% tip amount.
Make everything with echo statements and list out the meal items and prices, the subtotal, tax, tip, and grand total.

I have created this code:

<h3>Restaurant meal and prices</h3>

<?

$PastaDPina = 13;
$pepsi = 8;
$cake =4;
$entree = 11.2;

echo "PastaDPina: ". $PastaDPina."$<br>";
echo "Pepsi Cola: ".$pepsi."$<br>";
echo "Cake: ".$cake."$<br>";
echo "Entree: ".$entree."$<br>";

$total=$PastaDPina+$pepsi+$cake+$entree;
echo "<hr>";
echo "Total price is: <b>".$total."</b>";

?>

So i have listed out the meal items and prices and total. I do not know exactly how to list out subtotal, tax, tip, and grand total. Also how can i create A float variable for the 8% sales tax, and another one for the customer's 15% tip amount.? This is my third lesson on php

Hi,

Please have a look at the following code.

If you are using double quotes for your strings you do not need to do ".variable." around the variables.

Hope this helps,

John
