Question

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?

Answer 1

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.
