How to show the price depending on the selected weight?

Question

WordPress

On the page of the store and individual products, you need to display the price select and show the price of the selected weight instead of the main price. A variable product allows you to select a price, but shows it separately, and a range is displayed instead of the base one. In addition, you need to display this choice not only on the product page, but also on the store itself. It is necessary, in general, as here: theartoftea.ru/greentea Plugin
or not - it doesn't matter.
