Hi @iwona12,
By default the prices in WooCommerce for variations will display above the add to cart button when the variation or a combination of variations is selected.

To change how pricing is displayed within WooCommerce you would possibly need to be comfortable writing custom code to alter the plugins default display locations to suit your specific projects requirements if you could not locate a ready made plugin which could change what you require.
If you require assistance with any custom development work if you reach out to one of the official WooCommerce development partners they should be able to help with any changes your desired change of display may require.
