To discourage guessing on a multiple choice test, a teacher assigns 5 points for a correct answer, and –2 points for an incorrect answer, and 0 points for leaving the questioned unanswered. What is the score for a student who had 22 correct answers, 15 incorrect answers, and 7 unanswered questions?

Respuesta :

Answer:

Step-by-step explanation:

Correct Answer = 5

Incorrect Answer = -2

Unanswered = 0

22 correct answers = 22*5 = 110

15 incorrect answers = 15*-2 = -30

7 unanswered = 7*0 = 0

Add all the answers up : 110-30+0

Score = 80
