Jerry had 40 action figures and 15 books on a shelf in his room. 

This means that there were a total of 55 items on the shelf. 

Later he added 44 more books to the shelf. 

This means that there are now a total of 99 items on the shelf. 

Now we need to find out how many more books than action figures are on his shelf. 

To do this, we need to find out how many action figures are on the shelf. 

We know that there were originally 40 action figures on the shelf. 

We also know that there are now 99 items on the shelf. 

This means that there are 59 action figures on the shelf. 

Now we need to subtract the number of action figures from the total number of items on the shelf. 

99 - 59 = 40

This means that there are 40 more books than action figures on the shelf.
