To calculate the simple interest earned, you can use the formula:
\[ \text{Simple Interest} = P \times r \times t \]
Where:
- \( P \) = principal amount (the initial amount of money) = $2,000
- \( r \) = annual interest rate (in decimal) = 7% = 0.07
- \( t \) = time in years = 3
Now, plug the values into the formula:
\[ \text{Simple Interest} = 2000 \times 0.07 \times 3 \]
Calculating it step by step:
- \( 2000 \times 0.07 = 140 \)
- \( 140 \times 3 = 420 \)
Thus, the simple interest earned after 3 years is $420.
