Simple Interest Worksheet With Answers For Easy Learning
Table of Contents :
Understanding simple interest can be quite straightforward, especially when using a worksheet format for easy learning. This blog post will guide you through what simple interest is, how to calculate it, and provide an example worksheet along with answers to help solidify your understanding. So let's dive in! 📚💡
What is Simple Interest?
Simple interest is a method of calculating the interest charged or earned on a principal amount over a specific period. The formula to calculate simple interest is:
[ \text{Simple Interest (SI)} = P \times r \times t ]
Where:
- P = Principal amount (the initial amount of money)
- r = Rate of interest (in decimal form)
- t = Time (in years)
Why is Simple Interest Important?
Simple interest is commonly used in various financial contexts, such as loans, savings accounts, and investments. It’s essential because it helps individuals understand how much they will pay or earn over time. 📈💰
Examples of Simple Interest Calculation
Let’s break it down with a couple of examples.
-
Example 1: Personal Loan
- Principal (P): $1,000
- Rate (r): 5% per year (0.05 in decimal)
- Time (t): 3 years
Using the formula:
[ SI = 1000 \times 0.05 \times 3 = 150 ]
Thus, the simple interest on this loan over three years would be $150.
-
Example 2: Savings Account
- Principal (P): $2,500
- Rate (r): 4% per year (0.04 in decimal)
- Time (t): 2 years
Using the formula:
[ SI = 2500 \times 0.04 \times 2 = 200 ]
Therefore, the simple interest earned in this case would be $200.
