Dear Brainfinity teams,

With the new month comes a new detective task to think about! But knowing that this is an area where you excel, we have no doubt that you will be able to solve this task with ease.

Some teams performed exceptionally well in the previous task, but unfortunately, several teams logged into the stock market using the personal email addresses of team members or the names of teachers who are mentors for multiple teams, even though the instruction was to log in with the team’s email and name. We couldn’t determine which teams did this, so they are not on the list. Please send us an email to info@brainfinity.org with your response and evidence of which teams are involved.

On the platform, you can find a new problem, the third so far. If you solve this one, you can qualify for the Brainfinity challenge.

In this problem, your task is to interpret the data of an interesting prediction. Take a careful look at the given table and try to answer the given questions.

The deadline for solving this problem is December 20th, so don’t miss the opportunity to qualify your team for further placement in the competition, i.e., for the Brainfinity challenge.
