Finally, let's check which branch has the most opened accounts per client. In other words, which branch does the best job of meeting or exceeding Solbank's KPI?


Create a function named most_opened_accounts_per_client that takes one argument: df, the data frame we'll be using (bank_branches_2017 or bank_branches_2018). This function should return the name of the branch with the most opened accounts per client (a ratio of two columns).

For each branch, we can calculate accounts_per_client as follows:

df$accounts_per_client <- df$opened_accounts/df$number_of_clients
