Answer:
She would be using 16 oz of water.
Explanation:
based on the information given, she used 4 times the amount of contact solution as before, so had to multiply all other ingredient amounts by 4, so that would mean she now has to use 32 oz of glue, 12 oz of contact solution, 4 oz of baking soda, and 16 oz of water.
I am 100% sure this answer is correct
