Question

Hugh has to earn at least $400 to meet his fundraising goal. He has only 100 books that he plans to sell at $8 each. Which inequality shows the number of books, x, Hugh can sell to meet his goal?

20 ≤ x ≤ 400
40 ≤ x ≤ 100
50 ≤ x ≤ 400
50 ≤ x ≤ 100

Answer 3

The question says that Hugh has a total of 100 books, so we already know he can't sell more than 100 books; 100 books is the most books that Hugh can sell--that's half of the problem.
What about the least number of books Hugh can sell (in order to meet his goal)?
Hugh wants to raise $400, and each book will sell for $8. So, the least number of books Hugh can sell would be equal to $400/$8 per book

Now that you have the least number of books and the most number of books Hugh can sell, you should be able to write the inequality representing this range of books
