Suppose that $2000 is invested at a rate of 5.1%, compounded semiannually. Assuming that no withdrawals are made, find the total amount after 6 years.
Do not round any intermediate computations, and round your answer to the nearest cent.

Solution:

The formula for compound interest, including principal sum, is:

Where,

A = the future value of the investment/loan

P = the principal investment amount

r = the annual interest rate (decimal)

n = the number of times that interest is compounded per unit t

t = the time the money is invested

From given,

p = 2000

t = 6 years

n = 2 (  compounded semiannually)

Substituting the values we get,

Thus the total amount after 6 years is $ 2705.5649

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
