How can i set my custom calculated price as actual sell price to basket in Woocommerce

Hello I am calculating price on the basis of total amount. I want to add after discount price as my sell price for product. so when i click on the add to cart button it should show the after discount price.

Here’s my html sturucture that i have created accoding to my requirenment:

<div class="woocommerce-variation-price">
    <span class="price-incvat" style="text-decoration:line-through;">
        <span class="woocommerce-Price-amount amount">
            <bdi>
                <span class="woocommerce-Price-currencySymbol">£</span>
                531.36
            </bdi>
        </span> 
            Inc. VAT
        </span><br>
        <span class="price2" style="text-decoration:line-through;">
            <span class="woocommerce-Price-amount amount">
                <bdi>
                    <span class="woocommerce-Price-currencySymbol">£</span>
                    442.80
                </bdi>
            </span> 
            Exc. VAT
        </span><br>
        <span class="price-incvat newprice">
            <span class="woocommerce-Price-amount amount">
                <bdi>
                    <span class="woocommerce-Price-currencySymbol">£</span>
                    478.22
                </bdi>
            </span> 
            Inc. VAT
        </span><br>
        <span class="price2 newprice">
            <span class="woocommerce-Price-amount amount">
                <bdi>
                    <span class="woocommerce-Price-currencySymbol">£</span>
                    398.52
                </bdi>
            </span>
            Exc. VAT
        </span>
    </div>

Here’s defalut html sturucture of Woocommerce

<div class="yith_wapo_group_total
        " data-product-price="442.8" data-product-id="205692">
<table>
<tbody><tr class="ywapo_tr_product_base_price">
<td data-nosnippet="">Product price</td>
<td data-nosnippet=""><div class="yith_wapo_group_product_price_total"><span class="price amount">£442.80</span></div></td>
</tr>
<tr class="ywapo_tr_additional_options">
<td data-nosnippet="">Additional options total:</td>
<td data-nosnippet=""><div class="yith_wapo_group_option_total"><span class="price amount">£0.00</span></div></td>
</tr>
<tr class="ywapo_tr_order_totals">
<td data-nosnippet="">Order total:</td>
<td data-nosnippet=""><div class="yith_wapo_group_final_total"><span class="price amount">£442.80</span></div></td>
</tr>
</tbody></table>
</div>

And here’s my Jquery code to calculate dicosunt price:

jQuery(function ($) {
$('.yith_wapo_group_final_total .price.amount').on("DOMSubtreeModified", function () {
var price_ele = jQuery(".woocommerce-variation.single_variation .woocommerce-variation-price");
var price_ele_simp = jQuery(".new-price-simple");
var add_price1 = jQuery(".yith_wapo_group_final_total .price.amount").text().replace(/£/g, "");
var add_price = add_price1.replace(/,/g, "");
var inc = (add_price * 20) / 100;
var inc_price = parseFloat(add_price) + parseFloat(inc);
if(bundleproduct != '')
{
var bundleExcVatFinalPrice = parseFloat(add_price) - (add_price * bundleproduct);
var bundleIncVatFinalPrice = parseFloat(bundleExcVatFinalPrice) + (bundleExcVatFinalPrice * 0.20);
if (add_price1 != 0 && price_ele.text() != "") 
   {
    price_ele.html('<span class="price-incvat" style="text-decoration:line-through;"><span           class="woocommerce-Price-amount amount"><bdi><span class="woocommerce-Price-currencySymbol">£</span>' + numberWithCommas(inc_price.toFixed(2)) + '</bdi></span> Inc. VAT</span></span><br><span class="price2" style="text-decoration:line-through;"><span class="woocommerce-Price-amount amount"><bdi><span class="woocommerce-Price-currencySymbol">£</span>' + numberWithCommas(add_price) + '</bdi></span> Exc. VAT</span><br><span class="price-incvat"><span class="woocommerce-Price-amount amount"><bdi><span class="woocommerce-Price-currencySymbol">£</span>' + numberWithCommas(bundleIncVatFinalPrice.toFixed(2)) + '</bdi></span> Inc. VAT</span></span><br><span class="price2"><span class="woocommerce-Price-amount amount"><bdi><span class="woocommerce-Price-currencySymbol">£</span>' + numberWithCommas(bundleExcVatFinalPrice.toFixed(2)) + '</bdi></span> Exc. VAT</span>');
   }
else if (price_ele.text() == "") 
   {
    price_ele.html('<span class="price-incvat" style="text-decoration:line-through;"><span class="woocommerce-Price-amount amount"><bdi><span class="woocommerce-Price-currencySymbol">£</span>' + numberWithCommas(inc_price.toFixed(2)) + '</bdi></span> Inc. VAT</span></span><br><span class="price2" style="text-decoration:line-through;"><span class="woocommerce-Price-amount amount"><bdi><span class="woocommerce-Price-currencySymbol">£</span>' + numberWithCommas(add_price) + '</bdi></span> Exc. VAT</span><br><span class="price-incvat"><span class="woocommerce-Price-amount amount"><bdi><span class="woocommerce-Price-currencySymbol">£</span>' + numberWithCommas(bundleIncVatFinalPrice.toFixed(2)) + '</bdi></span> Inc. VAT</span></span><br><span class="price2"><span class="woocommerce-Price-amount amount"><bdi><span class="woocommerce-Price-currencySymbol">£</span>' + numberWithCommas(bundleExcVatFinalPrice.toFixed(2)) + '</bdi></span> Exc. VAT</span>');
   }
}
}, 350);
});
});

Now What i want is.. when i click on add-to-cart button it should take span with class “price2 newprice” that is “398.52” in according to html given above.

Attched images for better understanding:
Before adding to cart

After clickeing basket button (It should show “398.52” price here

$('.yith_wapo_group_total').attr('data-product-price', bundleExcVatFinalPrice);
$('.yith_wapo_group_final_total .price amount').attr('data-product-price', bundleExcVatFinalPrice);
