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=3? Explain your selection. $100 V=2 $100 O 1 2 3 4 5 6 a) V=100(P/A, i, 6)-100(P/F,i,4) c) V= [100+P(P/A,i,6)]*(F/P,i,3)-100 b) V= 100(F/A,i,3)+P(P/A,1,3) d) V=100(F/A,i,6)*(P/F,i,3)-100
