A new museum director has been hired with the goal to make the museum more self$-$sustaining and less reliant on donations and government grants. One of the director's first actions was to ask the museum staff to put together detailed financial information on the individual activities. The result, shown in the accompanying table, indicates that the series operates at a loss.

$\backslash$table$[[$Neighborhood Outreach: Evening Lecture Series$],[$For the Year Ending June $30]]$

The museum director is considering a proposal by the head of the Neighborhood Outreach Program to keep the Evening Lecture Series but expand it by offering a Weekend Lecture Series as well. The Weekend Series would be offered in a single location downtown near the museum itself.

The program head estimates that the attendance of the combined Series $($Evening and Weekend$)$ ?would be double that of the current Evening Series. The revenue of the combined Series would be $90$ ?percent higher because of some price discounts that would be offered. Because the Weekend Series would be new, a more intensive advertising campaign would be required. The director estimates that advertising costs for the combined Series would be $150$ ?percent higher than their current level. Lecturer fees and expenses will increase by only $75$ ?percent, because of the larger rooms used on the weekend. Staff operating costs will increase by $25$ ?percent. Rental costs for the Weekend Series will be $$13,300$ ?annually. Total food $$nd beverage costs will increase by $60$ ?percent with the new Series. The larger program will require an increase in Museum overhead of $$9,300.$ ?Aliocated museum overhead for the combined Series will be $$36,300$ ?annually.
