Answer:
Hi, the answer would be that Peter has 570 pages in total.
Explanation:
Since he has 5 books with 100 pages, you multiply 5 by 100
5 × 100 = 500
Next, Peter has 7 books with 10 pages each, so you multiply 7 by 10.
7 × 10 = 70
Next, you can add them together to get the total.
500 + 70 = 570
570 is the total.
Hope this helps!
