  • Five years ago, an alumnus of a university donated $50,000 to establish a permanent endowment for scholarships. The first scholarships were awarded 1 year after the contribution. If the amount awarded each year, that is, the interest on the endowment, is $4500, the rate of return earned on the fund is closest to: (a) 7.5% per year (b) 8.5% per year (c) 9% per year (d) 10% per year
    What are the values of the engineering economy symbols P, F, A, i, and n in the following spreadsheet or TVM calculator functions? Use a “?” for the symbol that is to be determined.a. FV(8%,10,2000,-10000)b. PMT(12%,30,16000)c. PV(9%,15,1000,700)d. n(8.5,5000,-50000,20000)
    Due to the high crime rate in the city center, the state council in partnership with the police has installed CCTV in several “hotspot” areas. The installation of the CCTV cost USD1000000. The cost of CCTV maintenance in the first year is USD500,000, USD700000 in the second year, USD950000 in the third year, USD990000 in the fourth year and costs are realized at the end of each year. On the other hand, the installation of CCTV will help to reduce crime in that area and is predicted to bring about a benefit of USD2000000 for the first and second year and a benefit of USD 3000000 for the third and fourth year. At the end of the fourth year, the CCTV will be replaced by a new one and it can be resold as second hand for USD200000. Assume the discount rate of 3% is used.  Calculate the present value of net benefits assuming that the benefits are realized at the beginning of each of the three years. Also, draw the timeline of benefits and costs.
