Problem Solving Example:You are the manager of an apartment complex which holds $150$ units. The amount of rent collected varies on the size of the unit. The price of rent ranges from $$40,000$ a year to about $$80,000$ a year. In the span of $12$ months there are expenses paid for the upkeep and in some cases renovation of units when the residents move out.The following table has been provided to you and the owner has asked that you provide him with the following information based on $15$ randomly selected units $($Units $117,48,31,126,13,24,144,60,97,84,52,19,5,75,$ & $2)$ Cash InProbabilityRandom NumbersCash outProbabilityRandom Numbers$$40,00040\%0-49$$$35,00050\%0-89$$$55,00020\%50-129$$$70,00030\%90-150$$$80,00015\%130-150$ Based on the information provided, develop a short run simulation for the net cash and state the percentage of chance occurrences. Then calculate the ROI for each unit.Which units have the highest ROIWhich units have the least ROIIf the income for unit $144$ decreased by $15\%$ what would be the new ROI?What is the total Net cash flow and ROI for these $15$ units?
