2. Compute the equivalent future and present worth for the cash flow in the following diagram with i=9% 0 2 s S 18600 3. Given the following cash flow series, which of the following equation(s) can be used to find out the equivalent worth V at n=4? Explain your selection. V=? Itit $100 $100 a) V=100(P/A, 1, 5)-100(P/E 1,4) b) V= [100+A(P/A,1,3)]*(F/P,1,4)+100(P/F,1,1) c) V= 100(F/A,1,4)+P(P/A,1,4) d) V=[100(P/A,1,5)+100]*(F/P,1,4)
