Monique is reading a book. The table shows how the number of pages remaining in the book is changing over time.
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
The equation that describes the relationship between time in hours (t) and the number of pages remaining (N) can be found by determining the pattern in the table.
The number of pages remaining is decreasing by 40 each hour. This means that for every hour that passes, 40 pages are read.
To find the equation, we can start with the initial number of pages remaining (360) and subtract 40 for each hour that passes.
Therefore, the equation that describes the relationship between t and N is:
N = -40t + 360.
So, the correct answer is D. N = 40t - 360.
