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 $$12,000$ annually. Total food and beverage costs will increase by $60$ percent with the new Series. The larger program will require an increase in Museum overhead of $$8,000.$ Allocated museum overhead for the combined Series will be $$35,000$ annually.
