Question

How many days will it take Carlos to read a book with 156 pages, if Carlos is trying to read 12 pages of his book a night?

Answer 1

See a solution process below:

Explanation:

We can write the equation to solve this problem as:

`d = g/p`

Where:
- `d` is the number of days it will take to read the book, what we are solving for in this problem.
- `g` is the number of pages in the book: `156" pages"` for this problem.
- `p` is the number of pages read per day: `(12"pages")/"day"` for this problem.

Substituting and calculating `d` gives:

`d = (156" pages")/((12"pages")/"day")`

`d = (156" pages"" day")/(12"pages")`

`d = (156color(red)(cancel(color(black)(" pages")))" day")/(12color(red)(cancel(color(black)("pages"))))`

`d = (156" day")/12`

`d = 13" days"`

It should take Carlos 13 days to read the book.
