Jose has made a comic book collection that he keeps among five shells with an equal number in each shelf. His father add 20 comic books to the bottom shelf so now the shelf has 125 books how many total books are in his collection use algebra solve this equation

Answer 1

Let's use algebra to solve the equation.

Let x be the number of comic books in each shelf.
The number of comic books in the bottom shelf before his father added 20 books is x, and after his father added 20 books, the number of comic books in the bottom shelf is x + 20.

The total number of comic books in his collection is the sum of the comic books in the five shelves, which is equal to 5x.

According to the given information, the number of comic books in the bottom shelf after his father added 20 books is 125. So, we can write the equation as:
5x = 125.

To solve for x, we divide both sides of the equation by 5:
x = 125/5
x = 25.

So, there are 25 comic books in each shelf, and the total number of comic books in his collection is 5x = 5*25 = 125.
