Step-by-step explanation: In the given case, Leila's target customers are the students in college campus. The college students do not have a lot of money to spend. Therefore, she should inform the audience about the inexpensive items in the menu that they can purchase.
She can also persuade them by telling them the services provided by cafe. The nearness of the cafe from the campus could save time of the students, thus it could be a good point to attract the students.
