Answer:
there will be 8 boxes filled and 7 extras books
The answer should be D) 18 because both 54 and 99 can divide by 3 and when you divide 54 by 3, you get 18 and that's the most bags you can have while still having both colors. Hope I could help.

4 · x^4 · x^4 · y
4 x^8 y
In words: four times x to the eighth times y
