wedding cakes...size related $.94 per guest. complexity related $31.62 per tier. order related $55.70 per order. data concerning two orders are listed here: Pyburn wedding # of guests 72, 4 tiers on cake and cost of purchased decorations $29.92. Smith wedding 189 guests, 5 tiers and cost of purchased decorations $68.75. Assuming all of the costs listed above are avoidable costs in the event that an order is turned down, what would the company need to charge for the pyburn wedding cake to just break even? I have no clue how to figure this out. thanks
