Peoples Bank offers 8% compounded continuously on CDs What amount invested now grow to 100,000 in 25 years Hint the continuous c
sleet_krkn [62]

Given:

Rate of interest = 8% compounded continuously.

Amount = 100,000

Time = 25 years

To find:

The principal value.

Solution:

Formula for amount after continuous compound interest:

A=Pe^{rt}

Where, A is amount, P is principal, r is the rate of interest and t is the number of years.

Putting A=100000, r=0.08, t=25 in the above formula, we get

100000=Pe^{0.08(25)}

100000=Pe^{2}

\dfrac{100000}{e^{2}}=P

\dfrac{100000}{7.389056}=P

On further simplification, we get

P\approx 13533.528

Therefore, the amount 13533.528 is invested.
