Solbank entered the European financial market two years ago. They opened multiple branches in each of several countries: Austria, Italy, Croatia, and Slovenia. Over the next few exercises, we'll analyze the number of clients and opened accounts in those branches for the years of 2017 and 2018.

Solbank currently wants to increase the number of financial accounts per client; this is its primary key performance indicator (KPI).
