An engineer wishes to have $3 million by the time he retires in 35 years. Assuming 8% nominal interest, compounded continuously, what annual sum must he set aside?

Respuesta :

Answer:

annual sum must he set aside $16209.42

Explanation:

given data

engineer wishes = $3 million

retires time = 35 years

nominal interest = 8%

solution

we get here effective annual rate that is

interest rate  = [tex]e^{r} - 1[/tex]  ...........1

interest rate  = [tex]e^{0.08} - 1[/tex]

interest rate  = 0.08328 = 8.33%

and

now we get annual sum must he set aside that is

amount = $3 million × [tex]\frac{rate}{(1+rate)^{t}-1}[/tex]

amount = $3000000 × [tex]\frac{0.0832}{(1+0.0832)^{35}-1}[/tex]

amount = $16209.42
