Unfortunately, we don't have a way to automatically display the current item price in your own page or Add to Cart option menus.
If different options have different prices, you can include the price as part of the option values in your Variants configuration. However, doing that means every time you change the price, you'd need to change it in two places on each Variant's configuation line (once in each actual price position and again in each value), and then you'd need to recopy-paste fresh Add to Cart code into your page, which is of course more work than just updating the price displayed elsewhere on your product page.
