Given Situation: What is the percent increase from the 20 students to the 30 students.
Solution:
=> Let’s find how many percent did it increase.
Let’s have 20 as the first total number of the students in the first counts.
=> Then it became 30 students, let’s find out how many students added.
=> 30 – 20 = 10, there are 10 students added
10 is 50% of 20, thus, 50% added to the number of students. And that makes it 30 as the total count.
Take 4 and multiply it by 5 (which you should be able to do in your head) and then add the two zeros back in so:
4•5= 20
20+0+0=
2000
