Jose has a comic book collection that he keeps among 5 shelves with an equal number on each shelf. His father adds 20 comic books to the bottom shelf, so the shelf now has 125 books. How many total books are in his collection? Use algebra to solve the equation. The answer is not 85,105!!!!

Answer 1

Let's call the number of comic books on each shelf n.
Since there are 5 shelves, the total number of comic books before his father added 20 was 5n.
After his father added 20, the number of comic books on the bottom shelf is n + 20.
We know that the total number of comic books after this addition is 125, so we can write the equation:
5n + n + 20 = 125
6n + 20 = 125
Subtracting 20 from both sides:
6n = 105
Dividing both sides by 6:
n = 105 / 6 = <<105/6=17.5>>17.5
This means there are 17.5 comic books on each shelf. Since we can't have half a comic book, the answer is not a whole number, so there appears to be an error in the question.
