Question

During the summer, you want to read at least 40 books. You have read 23 books so far this summer. What are the possible numbers of books you can read to reach or pass your goal? Write an inequality that you could use to answer this question. Let x represent the number of books you can read.

A) x + 23 ≥ 40
B) x - 23 ≥ 40
C) x ≤ 40
D) x ≥ 17

Answer 1

The correct answers are A and D.

Answer 2

The correct inequality to represent the scenario where a student has read 23 books and wants to read at least 40 books is x + 23 ≥ 40, which simplifies to x ≥ 17, meaning the student needs to read at least 17 more books.

Step-by-step explanation:

The student's question is about finding the possible numbers of additional books they need to read to achieve their summer reading goal, and writing this as an inequality.

Given that you have read 23 books and want to read at least 40 books, the number of additional books, x, that you need to read to meet or exceed your goal can be represented by the inequality x + 23 ≥ 40. To solve for x, you would subtract 23 from both sides of the inequality, which gives you x ≥ 17. This means you need to read at least 17 more books to reach your goal of 40 books.
