Cameron has a mask collection. He keeps 267 of the masks on his wall, which is 89% of his entire collection. What is the total number of masks in Cameron's collection?

300 masks

Step-by-step explanation:

If 267 is 89% of the whole amount, we can set up the following proportion:

, where x is the total amount of masks we need to find.

If we cross-multiply, we get 26700=89x. Divide both sides by 89, and we get 300. So, Cameron has a total of 300 masks in his collection.
