Model Sum - P3

My answer is 18 however the answer provided was 54. Please advise where I miss.
There are twice as many books in Box A than Box B. When some books are moved from Box A to Box B, the number
of books in Box B is 5 times as many as Box A. If there are 72 books in Box A at first, how many books are there left
in Book A in the end?
Zach's Answer:
Hi Theresa,
Your answer is correct, it should be 18. For the answer to be 54, the question should read "How many books are moved from Box A to Box B?" Let me know if you have further questions.
