Respuesta :

Answer:

individual he need save = $582.670

Explanation:

given data

time = 20 year

spend = $55,000

interest rate = 7 percent = 0.07

solution

we get here first  annuity factor that is express as

annuity factor = [tex]\frac{1}{rate} -\frac{1}{rate*(1+rate)^{time}}[/tex]   .........1

put here value

annuity factor = [tex]\frac{1}{0.07} -\frac{1}{0.07*(1+0.07)^{20}}[/tex]

annuity factor =  10.59%  

and here individual he need save will be

individual he need save = $55,000 × 10.59%

individual he need save = $582.670
