To discourage guessing on the multiple-choice exam a professor assigned 4 points for a correct answer, -4 points for an incorrect answer, and -1 for leaving the question blank. what is the score for a student who had 15 correct answers, had 5 incorrect answers, and left 5 questions blank?

35

Step-by-step explanation:

4 x 15 = 60

-4 x 5 = - 20

-1 x 5 = -5

60 - 20 - 5 = 35

The Student would make a 45.

Step-by-step explanation:

So, 1st, you multiply 15x4, that would = 60. so then you would multiply 5x4, that would equal 20. So, you will subtract 20 from 60, and you will get 40. 5x1=5, so then you will add 5+40, and get 45!!

Hope this helps!!! (:
