The independent variable in this scenario is the number of seats in the concert venue. This is because the event planner can control or manipulate the number of seats available in the venue, which in turn determines how many tickets can be sold for the event. By choosing a venue with a specific capacity, the event planner can directly impact the ticket sales and potentially increase the funds raised for the local charity.
