On a test the teacher gave +10 points for each correct answer, 0 points for a skipped question and -5 point for each incorrect answer. There were 10 questions on the test. Alex had 8 correct answers and 2 incorrect. What was his score??

Answer 1

-5 dollars plus lots of penalty!
+1
+30
70

Answer 2

1. Integer = whole number, positive or negative. 80 - 85 = -5; -5 is an integer, so it's the answer.

2. +2 and -2 cancel out, and 0 is 0. His score is +1.

3. 80+40=120. 120 - 90 = 30.

4. 8 correct answers = 80 points. 2 wrong ones = 10 points. 80 - 10 = 70. On a tangent, this teacher is unethical because he gives 5 free points for not answering a question. (0 - -5 =5)

Answer 3

Mr. Schultz= -5 (negative five) that means a bounced check
In golf= 1 over par
Marias score=30?
on a test=70
