Help me fast, plsss! Marlene made a table to relate the number of T-shirts to the total cost. How can you tell from the table that the relationship is not proportional?

INSERT_TEXT
A
The number of T-shirts increases in intervals of one.

B
The rule of multiplying by 8 works for all but 4 T-shirts.

C
The number of T-shirts increases by a different amount than the total cost does.

D
All of the numbers of T-shirts can be multiplied by the same amount to get the cost.
