Question

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

Answer 1

[AI-generated answer — Bot GPT 3.5]

To determine the relationship between t and N, we need to find the rate at which the number of pages is decreasing. This rate is given by the slope of the line connecting the points (0, 360) and (4, 200).

Slope = (change in N) / (change in t)
= (200 - 360) / (4 - 0)
= -160 / 4
= -40

So, the equation describing the relationship between t and N is:

N = -40t + 360

Therefore, the correct answer is:

b. N = -40t + 360
