Ayoga studio offers memberships that cost $60 per month for unlimited classes. the studio also accepts walk-ins, charging $10 per class. if someone attends enough classes in a month, the two options cost the same total amount. how many classes is that? what is that total amount?

Using the given, we can make an equation:
10c = 60
('c' represents the number of classes you've taken, and it equals 60 because we're trying to make the unlimited and the walk-in cost the same)

Divide both sides by 10:
10c/10 = 60/10
c = 6

You have to take 6 classes (or spend $60) in a month for both options to be equivalent.
