Answer: scores with 8 question wrong: 80-2(8)=64

Scores with x questions wrong: 80-2x

Step-by-step explanation:

Since Andrew loses 2 points for every question wrong. He would loose 2x8 or 16 points when getting 8 questions wrong. Since the best is out of 80 points, his final score would be 80-16 or 64 points
