(Long-term averages -Little's Law) Hotel The construction planner of a large hotel complex needs to determine the size of the guests parking lot. The complex attracts both business and leisure travellers so that occupancy rates are constant over time (days of the week and months). Given the size of the complex, demand for rooms is estimated at 300 rooms per day. Guests stay in the complex for 2 nights on average and about 2/3 of occupied rooms require a parking space. In addition, the planner wishes to maintain an average parking occupancy of no more than 75%. Using the above information, provide an estimate of the minimal number of parking spaces needed in this parking lot? After the complex opening, parking spaces are scarce due to a higher than anticipated guest flow. A year later, management agrees that the higher average demand of 390 rooms per day is expected to continue (is not a novelty effect) and plans to extend the parking lot. What is the minimal number of parking spaces that need to be added to guarantee an average occupancy no more than 75%? Assume that the predictions about the average length of stay in the complex and the fraction of guests arriving by cars materialized. Note that the number of parking spaces should be integer
