How to add custom value to variation price?

Question

PHP

Hello!
I use WooCommerce for products. I have a product (let's call it "Pizza"), it has 3 variations with its own price. I'm wondering how to add 100 rubles to this price in the product card using PHP code?

//функция для изменения цен с помощью числа
function wpp_price_plus() {
    return 100;
}

add_filter('woocommerce_product_variation_get_regular_price', 'wpp_custom_price', 99, 2 );
add_filter('woocommerce_product_variation_get_price', 'wpp_custom_price', 99, 2 );
function wpp_custom_price( $price, $product ) {
    return (float) $price + wpp_price_plus();
}

add_filter('woocommerce_variation_prices_price', 'wpp_custom_variable_price', 99, 3 );
add_filter('woocommerce_variation_prices_regular_price', 'wpp_custom_variable_price', 99, 3 );
function wpp_custom_variable_price( $price, $variation, $product ) {
     // Удаление кэшированной цены продукта
    wc_delete_product_transients($variation->get_id());
    return (float) $price + wpp_price_plus();
}

// Обработка кэширования цен
add_filter( 'woocommerce_get_variation_prices_hash', 'add_price_plus_to_variation_prices_hash', 99, 3 );
function add_price_plus_to_variation_prices_hash( $price_hash, $product, $for_display ) {
    $price_hash[] = wpp_price_plus();
    return $price_hash;
}
