Answer: A 6 pack of shirts for $67.80 is the better deal than the other one.
Step-by-step explanation: Is that one because you need to divide each of the prices to the number of shirts. First, lets start of with 22.78/2, 22.78 divided by the 2 pack of shirts is a quotient of $11.39.
Next lets do $67.80 / 6, So 67.80 divided by 6 equals $11.30. Meanwhile, 11.30 < 11.39 because of the sale. So that's why the 6 pack of shirts for $67.80 is the better deal.
