WILL GIVE BRAINLIEST!
To discourage random guessing on a multiple-choice exam, a professor assigns 7 points for a correct answer, โ3 points for an incorrect answer, and โ1 point for leaving the question blank. What is the score for a student who had 17 correct answers, had 6 incorrect answers, and left 4 questions blank?
STEP 1: Determine the number of points received for the correct answers.
Number of correct answers ร Number of points per correct answer = Number of points for correct answers.
_ ร 7 = _
STEP 2: Determine the number of points lost for the incorrect answers.
Number of incorrect answers ร Number of points per incorrect answer = Number of points for incorrect answers.
_ร (โ3) = _
STEP 3: Determine the number of points received for the unanswered questions.
Number of unanswered questions ร Number of points per unanswered question = Number of points for unanswered questions.
_ ร (โ1) = _
STEP 4: Add the three values together.
Points from
correct answers + Points lost from
incorrect answers + Points from
unanswered questions = Total score
_+ (_) + (_)= _points
