Mrs. Brown's homeroom:
(72 subscriptions) / (24 students)
= (72 / 24) subscriptions/students
= average of 3 subscriptions per student
Mrs. Garcia's homeroom:
(98 subscriptions) / (28 students)
= (98 / 28) subscriptions/students
= average of 3.5 subscriptions per student
Mrs. Garcia's homeroom sold more subscriptions PER STUDENT .
