A group of private investors borrowed $31,498,914 million to build 300 new luxury apartments near a large university. the money was borrowed at 7% annual interest, and the loan is to be repaid in equal annual amounts over a 40-year period. annual operating and maintenance expenses are estimated to be $4,274 per apartment. this expense will be incurred even if an apartment is vacant. the rental fee for each apartment will be $14,305 per year, and the worst case occupancy rate is projected to be 80%. investigate the sensitivity of annual profit (or loss) to changes in occupancy rate. express your answer in percent rounded to the nearest hundredths. Can this be made in PW method? Pls do so, thank you! (no table pls, any P/A, i%, n is fine)
