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.
Answer:16748.40
Step-by-step explanation: total supplies of last month= $12315
Total increasing in sales in this month =36%
Sales this month = 12315+ 36% of 12315
That's 12315+12315×36÷100
=16748.4004
That's appro.16748.40
So total sales of this month were $16748.40
The estimate of the problem would be 1/4 because 6/8- 1/2 you would get 1/4.
