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

Answer 1

The relationship between time (t) and the number of pages remaining (N) is decreasing by 40 pages every hour. Additionally, when t is 0, N is 360.

This means that the equation that describes the relationship is N = -40t + 360.

Therefore, the correct answer is B. N=-40t+360.
