Answer:

C. 18

Step-by-step explanation:

We can model the total number of pages in Roger's novel with the equation:

[tex]\rm total \ \# \ pages = (\# \ pages \ in \ intro ) + (avg \ \# \ pages \ per \ chapter)(\# \ chapters)[/tex]

Rearranging this to solve for # chapters, we get:

[tex]\rm (total \ \# \ pages) - (\# \ pages \ in \ intro ) = (avg \ \# \ pages \ per \ chapter)(\# \ chapters)[/tex]

[tex]\rm \dfrac{(total \ \# \ pages) - (\# \ pages \ in \ intro )}{(avg \ \# \ pages \ per \ chapter)} = (\# \ chapters)[/tex]

Plugging in the given values, we get:

[tex]\rm \# \ chapters = \dfrac{121-13}{6}[/tex]

[tex]\rm \# \ chapters = \dfrac{108}{6}[/tex]

[tex]\rm \# \ chapters = 18[/tex]

So, there are 18 chapters in Roger's novel.

Answer:18

Step-by-step explanation:There are total 121 pages in the novel and 13 pages is introduction. So subtract 13 from 121 which is 108 and then divide 108 by 6 so 18 is the answer.
