Hello! So for this question, all you have to do is add the numbers up to get the total cost. Groceries were $102.34 and the new shoes were $53.36. 102.34 + 53.36 = 155.7. Lorena spent $155.70 total.
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.
