A gym

Can you help Hazel manage the local gym?

In this story, you've just been hired as an SQL specialist. Are you ready to use your database skills to help Hazel, the manager of the local gym? She needs answers to business questions like these: Which membership types generate the most money? Which people need to buy a new membership? And how much money is spent on memberships by the average gym member?

Hint: In each exercise, you can see a sample of the data. Look in the right-hand menu, under the Database tab.

Have fun!
