js. How to increase the price of a product depending on its quantity?

Question

JavaScript

In general situations, there is a product, they have prices and quantity of goods, therefore 1 product = price of 1 product * per quantity. And so is the total sum of all goods. I'm not able to implement the price cheat, the quantity counter works. Please tell me how to implement, that's what is now available.

$(document).ready(function () {
                    var quantity = parseInt(<?=$arItem['QUANTITY']?>);
                    $('.minus').click(function () {
                        var price = parseInt(<?=$arItem['PRICE']?>);
                        var sum = price * quantity;
                        var count = sum - price;
                        count = count > price ? count : price;
                        $('#sum_<?= $arItem["ID"] ?>').html(count);
                        return false;
                    });
                });

Actually one step down does and no longer reduces.
