Answer 2

ExplainBot said that

Answer 3

nvm he said 525 not 545

Answer 4

Let's call the number of comic books on each shelf x.
So, there are x comic books per shelf, and since there are 5 shelves, the total number of comic books before his father adds 20 is 5x.
After his father adds 20 comic books to the bottom shelf, this shelf now has x + 20 comic books.
The total number of comic books is then 5x + (x + 20) = 125.
Combining like terms, we get 6x + 20 = 125.
Subtracting 20 from both sides, we get 6x = 105.
Dividing both sides by 6, we get x = <<17=17>>17.
So, the total number of comic books in his collection is 5x, or 5 * 17 = <<5*17=85>>85. Answer: \boxed{85}.
