Before we add unit economics to our AB-test funnel let’s calculate them separately.
In this exercise you need to calculate ARPU (Average Revenue Per User) of the control variation of the longer_onboarding_201803 AB-test.
As usual, submit the integer part of the answer. For example, if ARPU is 15.666 submit 15 as the answer.
About SQL Habit
Hi, it’s Anatoli, the author of SQL Habit. 
SQL Habit is a course (or, as some of the students say, “business simulator”). It’s based on a story of a fictional startup called Bindle. You’ll play a role of their Data Analyst 
and solve real-life challenges from Business, Marketing, and Product Management.
SQL Habit course is made of bite-sized lessons and exercises (you’re looking at one atm). They always have a real-life setting and detailed explanations. You can immediately apply everything you’ve learned at work.
