Answer:
C).Susan missed 4 questions on a quiz. Each question is worth 6 points. What is the change in points in her score?
Explanation:
Let's check all the equations again, we need something equals -24:
a) If Joseph owes 6$ to his mother he has -6$balance or 6$ payable. Then he pays 4 dollars, he will still have -2$ balance or 2 dollars payable. So this variant is not appropriate.
b)If the bathtub rises 6 millimeters in a minute, then 4 minutes will equal 24. So this variant is not appropriate
c) If we consider Susan could gain maximum A points and 1 question worth 6 points, then by missing 4 questions, it will equal 4*6=24 and she will have A-24 points total. It means she has 24 points less. That's why this missing will impact -24 points to her. This is true variant
d) if one batch requires 4 cups of blueberries, 6 batches will equal 24 cups totally. This variant is not appropriate.
