(ii) 9275 For 2 Years At 7 * % Per Annum. 2
Introduction
Simple interest is a fundamental concept in mathematics and finance, used to calculate the interest earned on a loan or investment over a specific period. In this article, we will delve into the world of simple interest calculations, focusing on a specific problem: calculating the interest earned on a principal amount of $9275 for 2 years at an annual interest rate of 7%.
What is Simple Interest?
Simple interest is a type of interest calculated only on the initial principal amount, without considering the interest earned on the interest itself. It is a straightforward and easy-to-understand concept, making it a popular choice for financial calculations.
The Formula for Simple Interest
The formula for simple interest is:
I = PRT
Where:
- I is the interest earned
- P is the principal amount (initial amount borrowed or invested)
- R is the annual interest rate (in decimal form)
- T is the time period (in years)
Applying the Formula to the Given Problem
Now that we have the formula, let's apply it to the given problem:
- P = $9275 (principal amount)
- R = 7% (annual interest rate) = 0.07 (in decimal form)
- T = 2 years (time period)
Plugging these values into the formula, we get:
I = 9275 * 0.07 * 2
I = 1297.50
Therefore, the interest earned on a principal amount of $9275 for 2 years at an annual interest rate of 7% is $1297.50.
Calculating the Total Amount
To find the total amount (principal + interest), we add the interest earned to the principal amount:
Total Amount = P + I
Total Amount = 9275 + 1297.50
Total Amount = 10572.50
Therefore, the total amount after 2 years is $10572.50.
Real-World Applications
Simple interest calculations have numerous real-world applications, including:
- Personal Finance: Calculating interest on loans, credit cards, and investments
- Business Finance: Determining interest on loans, investments, and deposits
- Economics: Analyzing interest rates and their impact on the economy
Conclusion
In conclusion, simple interest calculations are a fundamental concept in mathematics and finance. By understanding the formula and applying it to real-world problems, we can calculate interest earned on loans and investments. In this article, we applied the formula to a specific problem, calculating the interest earned on a principal amount of $9275 for 2 years at an annual interest rate of 7%. We also discussed the importance of simple interest calculations in personal finance, business finance, and economics.
