Answer:
Hmm..Tricky. One second!
Step-by-step explanation:
161
7*18 + 5*7
126 + 35 =

Set up the following equations:
x represents the amount of blue books needed, and y represents the amount of red books needed.
Solve the first equation by dividing both sides by 9:
Rebecca would need 61 pages if she used the blue book.
Solve the second equation by dividing both sides by 7:
Rebecca would need 78 pages if she used the red book.
Subtract the red book's pages from the blue book's pages:
Rebecca would need
17 more pages if she used the red book instead of the blue book.
