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

p =
`((19-15)/(15) )* 100`

Explanation:

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

So students added = 19 - 15 = 4

Now percentage of this addition will be p =
`(\frac{\text{students added}}{\text{total students before addition}})* 100`

p =
`((19-15)/(15) )* 100`

Answer 2

19-15 =4

4/15 = 0.266

0.266*100 = 26.6%

so 19-15/15
