Answer:
B. 16%
Explanation:
First, figure out the total number of people in Emily's class. To get the total amount of people in the class, add all of the numbers together.
5+6+4+3+5+2=25
We need the percentage of people who wore a red shirt. So, we need to find the whole first (100%). To get the whole to 100%, we need to find out what to multiply by 25 to get 100. This is easy because we automatically know 25x4=100.
Because we multiplied 4 by 25, now we have to multiply 4 by the number of students who wore a red shirt. 4 people wore a red shirt, so...
4x4=16
When you put 16 over 100, it looks like this: 16/100. Percentages are out of 100, so 16% of the class wore red shirts.
Hope this helps!! Have a great day :3
