Accepted Solution

A:

Answer:The amount of each withdrawal is $21368.46and amount of each withdrawal if the money must last 5 years is $17584.57Step-by-step explanation:given dataprincipal = $150000rate = 6% per year = (6/2 )× 100 = 0.03 compound semiannuallytime period = 4 year = 4× 2 = 8 half yearlytime period = 5 year = 5 × 2 = 10 half yearlyto find out The amount of each withdrawal and he amount of each withdrawal if the money must last 5 yearssolution first we solve to find payment to each withdraw in 4 year i.e. formulaamount = principal (rate ) / 1- [tex](1+rate)^{-time}[/tex] ...........1put all value rate principal time 8 half yearly in equation 1amount = principal (rate ) / 1- [tex](1+rate)^{-time}[/tex] amount = 150000 (rate ) / 1- [tex](1+0.03)^{-8}[/tex] amount = 150000 (0.03 ) / 1- [tex](1+0.03)^{-8}[/tex] amount = 21368.458324The amount of each withdrawal is $21368.46now we solve to find payment to each withdraw in 5 year i.e. formulaamount = principal (rate ) / 1- [tex](1+rate)^{-time}[/tex] ...........2put all valye rate principal time in equation 2amount = principal (rate ) / 1- [tex](1+rate)^{-time}[/tex] amount = 150000 (rate ) / 1- [tex](1+0.03)^{-10}[/tex] amount = 150000 (0.03 ) / 1- [tex](1+0.03)^{-10}[/tex] amount = 17584.575991amount of each withdrawal if the money must last 5 years is $17584.57
