Calculation with Jquery (function ($) {

    "use strict";

    $(document).ready(function () {

        $('.bookinginput').on('change', function(){

            var adults = $('#t_adults_qty').val(),
                    child =  $('#t_children_qty').val(),
                    pickup = $('#pick_up_list').val(),
                    priceBase = priceBooking.adult * adults,
                    priceChild = priceBooking.child * child;

            var price = priceBase + priceChild

            $('#price_total').val(price);
        })

    });
}(jQuery));


I will explain my code a bit, basically it is a small mathematical calculation based on the value of the inputs.

I have a json with the variable priceBooking, which has two values (Adult and Child), and I have several inputs with the numbers of the (adults and children).

I simply calculate the number of (Adults for the Adult price) the same with the children.

and the result I put it in the value of another hidden input (#price_total)

I would like to simplify this code or improve it. I want to be able to work with variables globally and not have to duplicate code.

Any suggestions?
pickup is defined, but never used.

You should terminate your statements with semicolons consistently.
