Answer:
It's 60.
Step-by-step explanation:
You can think of it like this:
If Jackson got a grade of 5% for 3 questions, then I can continuously multiply by 3 to get to 100.
3 questions is 5%.
6 questions is 10%.
12 questions is 20%.
24 questions is 40%.
48 questions is 80%.
Add another 12 questions for another 20%, and you get 100%.
48 + 12 is 60. 60 is your answer.
I put it this way so that way you can understand the basic concept of percentages.
