The number of pages remaining is decreasing by 40 pages each hour. To find the initial number of pages in the book, we can use the point (0, 360).
Therefore, the correct equation is:
N = -40t + 360
The answer is B.
Monique is reading a book. The table shows how the number of pages remaining in the book is changing over time.
