ER Business Case Interview in 20 mins?

As per the title says, I will have an interview for a ER internship (mid-small cap): before the real interview I will have 20 minutes to complete a short business case and then send it to the interviewers, who will discuss it with me during the interview. I really don't know what to expect, the only clue is that the job posting stated "ability to build an economic/ financial model in Excel is essential". I though of some DCF/multiples model but it's a very short time range, counting also the time to read the exercise text. What should I focus, in order to succeed? ​
