    Metadata details:
    filename: adjustment.rb
    path of file: ./repos/openfoodnetwork/app/models/invoice/data_presenter
    
    the code of the file until where you have to start completion: # frozen_string_literal: false

class Invoice
  class DataPresenter
    class Adjustm
    
      def display_taxes(display_zero: false)
        if included_tax_total.positive?
          amount = Spree::Money.new(included_tax_total, currency:)
          I18n.t(:tax_amount_included, amount:)
        elsif additional_tax_total.positive?
          Spree::Money.new(additional_tax_total, currency:)
        elsif display_zero
          Spree::Money.new(0.00, currency:)
        end
