Question

READING A BOOK

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?

Answer 1

The book starts with 360 pages and the number of pages remaining decreases by 40 every hour. Therefore, the equation that describes the relationship between t (time in hours) and N (number of pages remaining) is:

N = 360 - 40t
