How to change the price of a Woocommerce item using jQuery?

Question

JavaScript

I need to make 2 prices in the product card: per ton and per linear meter. Like here: A

live example at the link: https://vestametall.ru/sortovoj-i-fasonnyj-prokat/...
In order to implement all this, I used a simple code:

$('body').on('change', '.qty', function() {
    var w = $(this).data('w').toString().replace(/,/g, '.').replace(/ /g, ''),   /*вес погонного метра*/
    price = $(this).data('price').toString().replace(/,/g, '.').replace(/ /g, ''),    /*стоимость тонны*/
    count = $(this).val().toString().replace(/,/g, '.').replace(/ /g, ''),   /*количество тонн*/
    wrapper = $(this).closest('.quantity__input__wrapper');
console.log('price='+price+'count='+count+'wrapper='+wrapper);
    metr = parseInt(count/w);
    totalPrice = parseFloat(count*price);  /*получаем цену*/
console.log('metr='+metr+'totalPrice='+totalPrice);
    $('.woodmart-compare-btn').text(metr);
    $('.woocommerce-Price-amount').text(totalPrice); /*записываем цену куда то*/
  });

  $('body').on('change', '.quantity__input__metr', function() {
    var wrapper =  $(this).closest('.quantity__input__wrapper'),
    inp = $('.quantity__input__main', wrapper),
    w = inp.data('w').toString().replace(/,/g, '.').replace(/ /g, ''),
    metr = $(this).val().toString().replace(/,/g, '.').replace(/ /g, '');
    count = round(metr*w);
    inp.val(count).trigger('change');
  });

I get the price I want. But how do you get Woocommerce to take that price as the price of the product when adding to cart and for later checkout?
