Medal To discourage guessing on a multiple-choice exam, an instructor graded the test by giving 3 points for a correct answer, 0 points for an answer left blank, and -1 points for an incorrect answer. How many points did a student score who answered 36 questions correctly, answered 8 questions incorrectly, and left 6 questions blank? ? points
Well, the total number of points would be the correct answers *3 plus incorrect answers *-1. So it would be P=3*36-1*8=108-8=100 points.
The maximum number of points would be total number of questions *3. So Max=3*(36+8+6)=3*50=150 points possible.
Therefore, this student got 100 out of 150 points, or a 66%.
so the answer is 150 points?
No, the answer is 100 points out of a possible 150 points,
ok thank you
No problem.
is not the answer 96
Then you must have stated the question wrong, because 36*3=108 and the student got -8 from incorrect answers, therefore they got 100 points.
what about the questions they left blank
they get 0 points for a question left blank
so the answer is 100 points?
yes
thank you
