If Cody gives 13 bookmarks to Victoria, she will have 13 more bookmarks than him. However, Victoria must have 25 more bookmarks than Cody in the end. So, Cody has to give Victoria more bookmarks.
Number of more bookmarks that Cody has to give to Victoria
= (25 - 13) ÷ 2
= 12 ÷ 2
= 6
So after giving 13 bookmarks to Victoria, Cody has to give her another 6 more bookmarks so that she has 25 bookmarks more than him.
Total number of bookmarks that Victoria needs to get from Cody
= 13 + 6
= 19
Answer(s): 19
