1. Rachel picked 15 apples from her tree. 
2. If the tree had 41 apples initially, then 
3. How many apples are still there on the tree? 

We are looking for the number of apples that are left on the tree, so we want to solve for x. 

We know that Rachel picked 15 apples from her tree, so we can write: 

x - 15 = 41 

We want to solve for x, so we can add 15 to each side: 

x = 41 + 15 

x = 56 

So, there are 56 apples left on the tree.
