User helper functions in Lib classes

In rails 3, is it possible to use helper functions in library classes? for example, I have helper:

module CarHelper
  def total_price(cars)
    #Do something here
  end
end

In my Lib/my_library.rb

class MyLibrary
 def myFunc
   # I would like to use helper function total_price(cars) here
 end
