A group of private investors borrowed $34 million to build 250 new luxury apartments near a large university. The money was borrowed at 6% annual interest, and the loan is to be repaid in equal annual amounts over a 50-year period. Annual operating, maintenance, and insurance expenses are estimated to be $3,000 per apartment. This expense will be incurred even if an apartment is vacant. The rental fee for each apartment will be $12,000 per year, and the worst-case occupancy rate is projected to be 85%. Investigate the sensitivity of annual profit (or loss) to (a) changes in the occupancy rate and (b) changes in the annual rental fee
