Understanding Simple Interest
Simple interest is a type of interest that is calculated only on the initial principal amount of a loan or investment. It does not take into account the interest that has accrued over time. In this article, we will calculate the simple interest owed on a loan with a principal amount of $2800, a rate of 7.5%, and a time period of 4 1/2 years.
The Formula for Simple Interest
The formula for simple interest is:
I = PRT
Where:
- I = interest
- P = principal
- R = rate
- T = time
Plugging in the Values
Now that we have the formula, let's plug in the values given in the problem:
- Principal (P) = $2800
- Rate (R) = 7.5% = 0.075
- Time (T) = 4 1/2 years = 4.5 years
Calculating the Interest
Now we can calculate the interest using the formula:
I = PRT = $2800 x 0.075 x 4.5 = $1002
Rounding the Interest
Since we are asked to round the interest to the nearest cent, we can round $1002 to $1002.00.
Conclusion
In this article, we calculated the simple interest owed on a loan with a principal amount of $2800, a rate of 7.5%, and a time period of 4 1/2 years. We used the formula for simple interest and plugged in the values to calculate the interest. The result was $1002.00.
