There are 180 students at the school
Step-by-step explanation:
If 10% of the students like the color purple, then 100-10 = 90% do not like the color purple.
Students * percentage that do not like = students that do not like
students * 90% = 162
Change to decimal form
students *.90 = 162
Divide each side by .90
students *.90/.90 = 162/.90
students = 180
There are 180 students at the school
