Option 1: PV = $400,000
Option 2: Receive (FV) $432,000 in one year
PV = FV(1/(1+i)^n), where i= 8% = 0.08, n = 1 year
PV = 432,000(1/(1+0.08)^1) = $400,000
Option 3: Receive (A) $40,000 each year fro 20 years
PV= A{[1-(1+i)^-n]/i} where, n = 20 years
PV = 40,000{[1-(1+0.08)^-20]/0.08} = $392,725.90
Option 4: Receive (A) $36,000 each year from 30 years
PV = 36,000{[1-(1+0.08)^-30]/0.08} = $405,280.20
On the basis of present value computations above, option 4 is the best option for Kerry Blales. This option has the highest present value of $405,280.20
