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?
So she had 17 correct and that 85 points, left three points and so it doesn’t deduct, she had five left over and so that’s -10 points so 75 now, she got eight out of ten, so 75+40 = 115, minus 4 so 111 is the answer.
