Answer:
80 points
Explanation:
Total percentage is always 100%
Total points is 400
The research paper has a weight of 20% of the total (which is 400 points).
The highest possible points is 20% of 400
First, we need to convert percentage to decimal by dividing by 100. Then we will multiply that decimal with 400. Shown below:
20% = 20/100 = 0.2
Now,
0.2 * 400 = 80 points
So, she can earn 80 points for her research paper
