Reasoning and answer: Helen won twice as many games as Betsy's 5 so Helen won 2 * 5 = 10 games. Susan won three times as many games as Betsy's 5 so Susan won 3 * 5 = 15 games. When you combine their wins, together they won 5 + 10 + 15 = 30 games total.
The answer: 30

Since Siena bookmarks 30 website pages from the research she does on her browser every day, at the end of March, with 31 days, she would have bookmarked 30 * 31 = 930 pages. If Siena already has 400 bookmarked pages in her bookmarks library now, she will have 930 + 400 = 1330 pages in her bookmarks library at the end of March.
The answer: 1330
