Final answer:
Adam got the better grade as he scored 72% (36 out of 50), which is higher than Beth's score of 60% (36 out of 60).
Step-by-step explanation:
The question involves comparing the scores of two students, Adam and Beth, in relation to the total possible points for their respective quizzes. To determine who got the better grade, we calculate the percentage score for each student by dividing their score by the total possible points and then multiplying by 100.
For Adam: (36 / 50) × 100 = 72%
For Beth: (36 / 60) × 100 = 60%
Comparing these percentages, we see that Adam's score is higher than Beth's. Therefore, Adam got a better grade because his percentage score is higher.
The correct answer to the question is: a. Adam, because a 36 out of 50 points means you scored closer to full points than a 36 out of 60 points.
