Question

A girl read a book that had 1,159 pages. She read 72 pages on the first day. She then read 40 pages per day until she finished the book. Which equation can be used to find how many more days, d, it took her to read the book after the first day?

Answer 1

The girl read 1,159 - 72 = 1,087 pages after the first day.

Let d be the number of days after the first day that she took to finish the book.

The total number of pages she read on these d days is 40d.

The equation that can be used to find how many more days it took her to read the book after the first day is:

40d = 1,087

Solving for d:

d = 1,087/40

d ≈ 27.175

Therefore, it took her approximately 27 more days to finish reading the book after the first day.
