The total of T-shirts is proportional to the total of players, which means 15 players = 15 t-shirts.
A proportion describes the number of elements from one category compared to the number of elements in another. For example, if there are 15 boys and 15 girls in a classroom the number of girls and boys is proportional.
These have a proportional relationship because for every player it is expected there is a determined t-shirts number and this number can only increase if the players increase.
1 t-shirt per player:
36 players = 36 t-shirts
2 t-shirts per player:
36 players = 72 t-shirts
