Answer: The student performed best on Quiz 2.

Step by step solution

01

Calculate the Percentage Score for Quiz 1

First, we will calculate the percentage score for Quiz 1. Divide the score earned (18) by the total possible points (25) and multiply by 100: Percentage Score for Quiz 1: \(\frac{18}{25} \times 100 = 72\%\)
02

Calculate the Percentage Score for Quiz 2

Now, we will calculate the percentage score for Quiz 2. Divide the score earned (32) by the total possible points (40) and multiply by 100: Percentage Score for Quiz 2: \(\frac{32}{40} \times 100 = 80\%\)
03

Calculate the Percentage Score for Quiz 3

Finally, we will calculate the percentage score for Quiz 3. Divide the score earned (35) by the total possible points (50) and multiply by 100: Percentage Score for Quiz 3: \(\frac{35}{50} \times 100 = 70\%\)
04

Compare the Percentage Scores

Now that we have the percentage scores for all three quizzes, let's compare them: Quiz 1: 72% Quiz 2: 80% Quiz 3: 70% From the comparison, it is evident that the highest percentage score is for Quiz 2, at 80%. So, the student performed best on Quiz 2.
