Question

Samantha's notebook has 14 pages more than three times as much as Lisa's notebook. If Samantha's notebook has 260 pages, how many pages are there in Lisa's notebook?

Answer 1

Lisa's notebook has `82` pages.

Explanation:

If we represent the number of pages in Lisa's notebook as `x`, then the number of pages in Samantha's notebook will be `(3x+14)`, which we know to be `260`. Hence:

`3x+14=260`

Subtract `14` from each side.

`3x=246`

Divide each side by `3`.

`x=82` which is the number of pages in Lisa's notebook.
