To calculate the compound interest.
Answer to Problem 36E
$8463
Explanation of Solution
Given Information: P = $8550, r = 3.5%, t = 20 years
Formula Used:Compound Interest CI= A − P, Amount A=
Calculation:
Compound interest is the interest calculated on the principal and the interest accumulated over the previous period. It is different from the simple interest where interest is not added to the principal while calculating the interest during the next period. Compound interest finds its usage in most of the transactions in the banking and finance sectors and also in other areas as well.
Compound Interest CI= A − P, Amount A=
Now find Amount A
P = $8550, r = 3.5%, t = 20 years
Amount A=
So,
Amount A=
So,
Amount A=$
So,
Amount A=$
Hence,
Amount = $17012.69
Compound Interest CI= A − P
CI = $17012.69 - $8550
Compound Interest CI = $8462.69
Nearest Compound Interest CI = $8463
