Jose has a comic book collection that he keeps among 5 shelves with an equal number on each

Question

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)

Answer 1

Let x be the number of comic books on each shelf.
There are 5 shelves, so there are a total of 5*x comic books in the collection before his father adds any.
After his father adds 20 comic books to the bottom shelf, there are x+20 comic books on that shelf.
The total number of comic books in the collection is now 5*x+(x+20)=125
Combining like terms, we get 6*x+20=125
Subtracting 20 from both sides, we get 6*x=105
Dividing both sides by 6, we get x=<<7=7>>7
There are 5 shelves with 7 comic books on each shelf, so there are a total of 5*7=<<5*7=35>>35 comic books in his collection. Answer: \boxed{35}.
