Final answer:
To calculate compound interest, the provided formula CI = P(1 + r/n)^(nt) - P is used. This requires details such as the principal amount, annual interest rate, compounding frequency, and time which were not provided in the question.
Step-by-step explanation:
Compound interest is calculated on the initial principal and also on the accumulated interest from previous periods. To find the compound interest, the formula CI = P(1 + r/n)^(nt) - P is used, where P is the principal, r is the annual interest rate, n is the number of times interest is compounded per year, and t is the time in years.
Unfortunately, as the original question doesn't provide the specific rate or time needed to calculate the compound interest on the given principal amounts, a complete numerical solution can't be given. Typically, one would follow these steps:
- Determine the principal amount, annual interest rate, number of times interest is compounded per year, and the time in years.
- Insert these values into the compound interest formula.
- Calculate the future value by raising the quantity (1 + r/n) to the power of nt.
- Multiply the principal by the calculated quantity.
- Subtract the principal to get the compound interest.
