Question

8. A teacher wanted to prevent students from guessing answers on a

multiple-choice test. The teacher graded 5 points for a correct answer, 0
points for no answer, and -2 points for a wrong answer. Giselle answered
-17 questions correctly, left 3 blank, and had 5 wrong answers. She also
got 8 out of 10 possible points for extra credit. What was her final score?

Answer 1

83

Explanation:

17 correctly answered questions x 5 points = 85 points

3 blank questions x 0 points = 0 points

5 wrong questions x -2 = -10 points

85 - 10 = 75 points

75 + 8 = 83
