At Glenridge High School, 20 percent of the
students are seniors. If all of the seniors attended
the school play, and 60 percent of all the students
attended the play, what percent of the non-seniors
attended the play?

40 percent

Step-by-step explanation:

60 - 20 = 40

Reasoning: The amount of seniors that attended was 20 percent, so 60 (total students) percent minus 20 percent is equal to 40 percent.

Hope this helps!
