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. it isnt 85,105, or 525

Answer 1

Let's assume that Jose has x comic books on each shelf before his father added 20 comic books to the bottom shelf.

Since each shelf has x comic books, the total number of comic books on the bottom shelf is x+20.

Before his father added the comic books, Jose had a total of 5*x comic books on all the shelves combined.

After his father added the comic books, the total number of comic books on all the shelves is 5*x + 20.

We know that the total number of comic books on the bottom shelf is 125.

So we can write the equation: x + 20 = 125.

Subtracting 20 from both sides of the equation, we get: x = 125 - 20 = 105.

Therefore, Jose has a total of 5*105 = <<5*105=525>>525 comic books in his collection.
