Question

Over the course of a year, a classroom went from 15 students to 19 students. Use the drop-down menus to build an equation that could be used to find the percent change, p , in the number of students.

Answer 1

Answer:

The percentage change is 26.7 % .

Step-by-step explanation:

Formula

$Percentage\ change = \frac{Change\ in\ value\times 100}{Initial\ value}$

Where change in value = Final value -  initial value

As given

Over the course of a year, a classroom went from 15 students to 19 students.

Here

Final value = 19

initial value = 15

Put in the above

change in value = 19 - 15

                            = 4

Put in the percentage formula

$Percentage\ change = \frac{4\times 100}{15}$

$Percentage\ change = \frac{400}{15}$

Percentage change = 26.7 % (Approx)

Therefore the percentage change is 26.7 % .
