APD stands for Amount Per Day. It is a measure we use to calculate how much the company receives from each guest on a per day basis.

One of our ships, the S.S. Minnow, is set to sail out of Marseilles, France on a 7-night cruise. Currently, the sailing departing 6/5/22 is behind where the comparable sailing (6/8/19) was booked same time three years ago in volume, but the rates we are charging this year so far are much higher. The 6/5/22 sailing is currently booked at $140 APD and is 50% full. This time three years ago, the comparable sailing (departing 6/8/19) was booked at a $100 APD and was 55% full. This 6/8/19 sailing achieved a $105 final APD and was 100% full at the time of departure.

a. At what APD do we have to sell the remaining inventory on the 6/5/22 sailing in order to match last years final APD on the 6/8/19 departure, assuming we will sail 100% full?
