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. (1 point)

3 answers

Let \( x \) be the number of comic books on each shelf. Since there are 5 shelves, the total number of comic books in the collection can be expressed as \( 5x \).

According to the problem, Jose's father adds 20 comic books to the bottom shelf, resulting in that shelf containing 125 books. Thus, we can set up the following equation for the bottom shelf:

\[ x + 20 = 125 \]

Now, we can solve for \( x \):

\[ x = 125 - 20 \] \[ x = 105 \]

Now that we know there are 105 books on each shelf, we can find the total number of books in the collection:

\[ \text{Total books} = 5x = 5 \times 105 = 525 \]

Therefore, the total number of comic books in Jose's collection is \(\boxed{525}\).

it not right

Let's go through the problem again step by step to find the correct answer.

  1. Let \( x \) be the number of comic books on each shelf.
  2. Since there are 5 shelves, the total number of comic books can be represented as \( 5x \).
  3. After adding 20 comic books to the bottom shelf, that shelf contains 125 books. So we can write the equation:

\[ x + 20 = 125 \]

  1. Now we need to solve for \( x \):

\[ x = 125 - 20 \] \[ x = 105 \]

  1. Now that we have determined that each shelf has 105 comic books, we can calculate the total number of comic books in the collection:

\[ \text{Total books} = 5 \cdot x = 5 \cdot 105 = 525 \]

So, the total number of comic books in Jose's collection is \(\boxed{525}\).
