Answer: It would most likely be D. 90
Step-by-step explanation: When you are dealing with grades, you have to know how to average them. First step is to add all of the points that he earned, this would be 80 + 100 + 100 + 100 + 100 = 480. After you find that, you have to divide it by 5 since he takes 5 tests. 480/5 = 96. I hoped this helped you.
