Rebecca wants to split a collection of eggs into groups of w. If each group has x eggs How many eggs does Rebecca have?
Rebecca has n eggs. 

She wants to split them into groups of w. 

That means she will have n/w groups. 

Each group has x eggs. 

That means the total number of eggs is n/w*x. 

We know that n/w*x = 22, so n = 22*w/x. 

Therefore, n = 22*11/2 = 242.
