The total number of items purchased is 12 + 12 + 12 = 36.
Since the football team will not pay tax on the items, the cost for the 36 items is the total cost.
Let C be the total cost of the items.
Then,
C/37 = cost per person
We need to find C.
Let T be the cost of a T-shirt, S be the cost of a sweatpants, and H be the cost of a sweatshirt.
Then,
C = 12T + 12S + 12H
We don't know the individual costs of the items, so we can't find C directly.
However, we know that the cost will be divided equally among 37 people.
So,
C/37 = (12T + 12S + 12H)/37
Multiplying both sides by 37:
C = 12T + 12S + 12H
The cost per person is:
(12T + 12S + 12H)/37
Since we don't know the individual costs of the items, we can't calculate the cost per person.
