Answer:

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.
