Challenge 1 / 1

Imagine our website provides paid access to content and allows users to subscribe. We integrated a payment system called Stripe that helps with it. When a new user subscribes, we send an API request to Stripe and it returns a response that contains all the necessary info about the user's subscription. The structure of the data looks like this:

$subscriptionData = array(
    "id" => "sub_1NiGuB2eZ",
    "object" => "subscription",
    "items" => array(
        "object" => "list",
        "data" => array(
            array(
                "id" => "si_OVHTBQE",
                "object" => "subscription_item",
                "price" => array(
                    "id" => "plan_OUwcmF6",
                    "object" => "price",
                    "amount" => 24.99,
                    "currency" => "USD",
                ),
            ),
        ),
    ),
);

Now we want to print the amount the user just paid on the page. How can we do it?
