Eileen likes to keep scrapbooks. She already has 4 scrapbooks filled with 40 pages each. If she fills 5 pages every month, how many months will it take her to fill up 2 more 40-page scrapbooks?
89
To find the number of months it will take Eileen to fill up 2 more 40-page scrapbooks, we need to calculate the total number of pages she needs to fill.
Eileen already has 4 scrapbooks filled with 40 pages each, which means she has a total of 4 x 40 = 160 pages filled.
Each month, Eileen fills 5 pages, so to determine the number of months it will take her to fill up 2 more 40-page scrapbooks, we need to calculate the remaining number of unfilled pages:
2 x 40 = 80 pages
To fill up 80 pages at a rate of 5 pages per month, we divide:
80 / 5 = 16 months
Therefore, it will take Eileen 16 months to fill up 2 more 40-page scrapbooks.
