Monique is reading a book. The table shows how the number of pages remaining in the book is changing over time.
READING A BOOK
Time (hours) Number of Pages Remaining
0 360
1 320
2 280
3 240
4 200
Which equation describes the relationship between t, the time in hours, and N, the number of pages remaining in the book?
A.
N=-40t-360
B.
N=-40t+360
C.
N=40t+360
D.
N=40t-360
To find the equation that describes the relationship between time (t) and number of pages remaining (N), we need to determine the rate at which the number of pages is decreasing per hour.
From the table, we can see that the number of pages remaining is decreasing by 40 pages every hour.
Therefore, the equation that describes the relationship is:
N = -40t + 360
So the correct answer is:
B. N=-40t+360
