On a final exam, each multiple-choice question is worth 4 points and each word problem is worth 8 points. Lorenzo needs at least 50 points on the final to earn a "B" in the class. Which inequality represents x, the number of correct multiple-choice questions, and y, the number of correct word problems, he needs to earn a "B"?
4x + 8y < 50
4x + 8y ≤ 50
4x + 8y > 50
4x + 8y ≥ 50
The correct inequality is: 4x + 8y ≥ 50
The inequality that represents the situation is:
4x + 8y ≥ 50
This is because Lorenzo needs at least 50 points on the final exam to earn a "B" in the class. The term "at least" implies that the total score must be greater than or equal to 50, which is represented by the greater than or equal to sign (≥) in the inequality.
