Question

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"?

Answer 1

D. 4x + 8y ≥ 50

Answer 2

The correct multiple choice questions (x) are 4 points each.
The correct word problems (y) are 8 points each.
Lorenzo needs AT LEAST 50 points.
Put all that information into an inequality and you get:
4x + 8y ≥ 50
