B.

C.
Each additional t-shirt being printed will increase the total cost by $11.
D.
Each additional t-shirt being printed will increase the total cost by 11%.

Answer 1

C. Each additional t-shirt being printed will increase the total cost by $11.

Explanation:

We know that the total cost of custom t-shirts, y, in dollars, for x t-shirts is given by:

`y = 11x + 25`

Here 11 is the price of the shirt, x is the number of shirts that are printed and 25 might be some additional charges.

For each additional shirt that is printed, the total price, y, will increase by $11 so the correct answer option is C.
