To calculate the simple interest, you can use the formula:
\[ \text{Simple Interest} = P \times r \times t \]
where:
- \( P \) is the principal amount ($20,000),
- \( r \) is the interest rate (8% or 0.08), and
- \( t \) is the time (5 years).
Now, plug in the values:
\[ \text{Simple Interest} = 20,000 \times 0.08 \times 5 \]
Calculating:
\[ \text{Simple Interest} = 20,000 \times 0.08 = 1,600 \]
Then,
\[ \text{Simple Interest} = 1,600 \times 5 = 8,000 \]
So the simple interest after 5 years is $8,000.
The correct response is:
$8,000.
