Elisa won 40 lollipops. She gave two to every student. She has at least 7 lollipops left. Write an inequality to represent the situation and solve

Question

I don't understand how to make a equation but, I do know how to make a graph for it.

Answer 1

For the graph:

 

S can = 16.5, so place a solid dot on 16.5.

S can < 16.5, so draw a solid line to the left.

Answer 2

40-2S≥7

 

You could use this inequality to solve for S (the number of students):

 

-2S≥-33

S≤33/2

or 

S≤16.5
