Answer 1

Explanation:

Let p represent the number of pages that she read on each day after the first day.

Reggie read a 400-page book in 5 days. On the first day, he read 120 pages. The means that the remaining number of pages would be 400 - 120 = 280

The number of days remaining would be 5 - 1 = 4

Since she read the same number of pages on each day after the first day, then

4p = 280

p = 280/4 = 70 pages
