Question: Janine read 5 books last month. This month, she read twice as many books. If each book has 10 pages, how many pages did Janine read in two months? Think carefully first, then make a decision:
Janine read 5 x 2 = 10 books this month. So, she read a total of 5 + 10 = 15 books. Therefore, she read 15 x 10 = 150 pages in all. So the answer is 150.
