Final answer:
To calculate the interest rate applied, we can use the formula for compound interest and solve for the interest rate using the given values.
Step-by-step explanation:
To calculate the interest rate applied, we can use the formula for compound interest:
Future Value = Present Value × (1 + Interest Rate)Number of Periods
In this case, we have the future value (P^(1),000,000), the present value (P300,000), and the number of periods (15 years). We need to solve for the interest rate:
Interest Rate = (Future Value / Present Value)1 / Number of Periods - 1
Plugging in the values:
Interest Rate = (P^(1),000,000 / P300,000)1 / 15 - 1
Simplifying this equation will give us the interest rate.
