4. Problem 3.76: For the following cash flows, we want to calculate the present worth (in year 0), using ju 10% per year. Which of thefollowing solution equations is not correct? Year Cash flow ($) 200 200 200 200 300 300 300 P-200 + 200(FYA, 10%,3) + 300(FYA, 10%,3)(PF, 10%,3) b. a. P-200(P/4,10%,4) + 300(P/A, 10%,3)(P/F,10%,3) c. P-200(FA, 10%,7) + 100(FA, 10%,3)](PF, 1096,6) d. P=[200(PA, 10%,7) + 100(PA I 0%,3)(PF, 10%,4)](F/P, 10%, 1) Problem 3.77: To establish a contingency fund to replace equipment after unexpected breakdowns, a manufacturer of thin-wall plastic bottles plans to deposit $100,000 now, and $150,000 two years from now into an investment account. If the account grows at 15% per year, then the equation that does not represent the future value of the account in year 5 is: 5. F= 100,000 (FP,15%,5) + 150,000(FP,15%,3) F=[100,000 (FP,15%,2) + 150,000](FP,15%,3) F-100,000 + 150,000(P/F,15%,2)(F/P,15%,5) F-100,000 (FP, l 5%,5) +150,000(F/P,15%,2) a. b. c. d
