S7-7 Compute weighted-average contribution margin (Learning Objective 4) Use the information from the FunTime Cruiseline Data Set. Suppose FunTime Cruiseline decides to offer two types of dinner cruises: regular cruises and executive cruises. The executive cruise includes complimentary cocktails and a five-course dinner on the upper deck. Assume that fixed expenses remain at $210,000 per month and that the following ticket prices and variable expenses apply: Regular Cruise Executive Cruise Sales price per ticket $50 $100 Variable expense per passenger $30 $ 40 Assuming that FunTime Cruiseline expects to sell four regular cruises for every executive cruise, compute the weighted-average contribution margin per unit. Is it higher or lower than a simple average contribution margin? (A simple average is calculated by adding both contribution margins per passenger together and dividing by two.) Why? Is it higher or lower than the regular cruise contribution margin calculated in S7-1? Why? Will this new sales mix cause FunTime Cruiseline's breakeven point to increase or decrease from what it was when it sold only regular cruises? S7-8 Continuation of S7-7: Breakeven (Learning Objective 4) Refer to your answer to S7-7. Compute the total number of dinner cruises that FunTime Cruiseline must sell to breakeven. Compute the number of regular cruises and executive cruises the company must sell to breakeven.
