Customer: "Currently I am paying $ 60.00 a month for my service. I would like to upgrade to the $ 80.00 service package because my new employer offers a 20% discount with your company. What would be the cost difference compared to what I am paying now if I upgraded?" Employee: "With your discount you would only pay _a month more for the upgraded plan." $ 4,00 $ 6.00 $ 22.00 $ 36.00 No difference
