You are on a committee to host a banquet for a major fundraising organization, which will consist of live music, a reception, a full meal [appetizer, entrée, vegetables, salad, soup, dessert and coffee or tea]. The band is $2500 for the evening. The other fixed costs include ice sculpture, USD 300, reception USD 2500, photographer, USD 750 and miscellaneous, USD 3,000. The meal cost is USD 45 per ticket. If ticket prices are USD 100, what is the breakeven number of ticket sales for the event? Now assume that the event planner takes ten percent of every ticket sale. Calculate the break even in this case and also find the contribution margin at breakeven sales?
