Kendi has a large collection of vinyl stickers, and each sticker has an animal on it or an emoji on it (but not both). In this collection, \(300\) of the stickers have animals on them, and \(1\) out of \(5\) of all of the stickers have animals on them. She would like to add more stickers to her collection so that there are \(3\) stickers with animals on them out of every \(10\) stickers.
If she can buy the stickers in packages of \(60\) stickers where \(21\) are animal stickers and the remaining are emoji stickers, how many whole packages does she need to buy?
