Question
**Simple Interest Calculation**

**Problem Statement:**
Fred started a new e-Commerce business and borrowed $14,800 for 10 years to get the business up and running. The interest is $4,440. Find the rate. Round to two decimal places, if necessary.

**Question:**
The interest rate for Fred's loan is _____%.

**Instructions:**
Assume that all interest is simple interest. Use the formula for simple interest to determine the interest rate.

**Simple Interest Formula:**
\[ I = P \times R \times T \]
Where:
- \( I \) = Interest
- \( P \) = Principal amount (initial loan)
- \( R \) = Rate of interest per year (as a decimal)
- \( T \) = Time (in years)

Given:
- \( I = 4,440 \)
- \( P = 14,800 \)
- \( T = 10 \) years

**Steps to Find the Rate:**
1. Substitute the known values into the simple interest formula:
   \[ 4,440 = 14,800 \times R \times 10 \]
2. To isolate \( R \), divide both sides of the equation by \( 14,800 \times 10 \):
   \[ R = \frac{4,440}{14,800 \times 10} \]
3. Calculate the value of \( R \).

**Final Calculation:**
\[ R = \frac{4,440}{148,000} \]
\[ R = 0.03 \]

**Convert the Rate to a Percentage:**
\[ R \times 100 = 3\% \]

**Answer:**
The interest rate for Fred's loan is **3.00%**.
