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. $100 V = ? 2 3 4 5 $100 a) V=100(P/A, i, 5)-100(P/F,i,4) (F/P,i,4)+100(P/F,i,1) c) V= 100(F/A,i,4)+P(P/A,1,4) (F/P,i,4) b) V= [100+A(P/A,i,3)]* d) V=[100(P/A,i,5)+100]*
