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

The revenue in the problem is equal to $400 that is to be made out of 100 books selling at $8 each. The minimum number of books he has to seel is $400/$8 per book of 50 books. The maximum number is 100 books. Hence the answer to this problem is 50 ≤ x ≤ 100.
