Customers arrive to Crystal River Day Spa and request combinations of two different types of treatments: 1) massage; 2) facial. Assume that these are the only two types of treatments offered by the day spa.

The overall demand rate is 86 customers per day.

All customers must first check-in at reception which takes on average 8 minutes.

45% of customers request a long massage whereas 30% of customers request a short massage. The remaining customers wish to only receive a facial.

The long massage lasts 105 minutes on average; whereas the short massage lasts 60 minutes on average. In both cases this includes the time for the massage therapist to prep the room, give the massage, and clean the room.

On average, 30% of the customers that request a long massage also request a facial and 30% of the customers who request a short massage also request a facial.

Facials are performed by an esthetician and take on average 80 minutes regardless of whether the customer received a massage. The day spa has 3 receptionists, 7 massage therapists, and 8 estheticians working at any time during its 12-hour workday, and at least that many rooms are available for each type of service. The price for a long massage is $150, the price for a short massage is $85, and the price for a facial is $95. Rounding instructions. Carry all calculations.
