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.

19-15 =4

4/15 = 0.266

0.266*100 = 26.6%

 so 19-15/15

p =

Step-by-step 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 =  

p =

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
