[AI-generated answer — Bot GPT 3.5]

Let's assign a variable to represent the number of comic books on each shelf. Let's call it "x".

Since Joe's father added 20 comic books to the bottom shelf and there are now 125 books total on that shelf, we can write an equation:

x + 20 = 125

Now, we can solve this equation for x:

x = 125 - 20

x = 105

So, there are 105 comic books on each shelf.

Since Joe has 5 shelves, we can calculate the total number of comic books:

Total number of comic books = Number of comic books per shelf x Number of shelves = 105 x 5 = 525

Therefore, the total number of comic books in Joe's collection is 525.
