To calculate the amount Benjamin receives after 8 years with simple interest, we use the simple interest formula:

$\text{Simple Interest} = P \times r \times t$

Where:

• $P$ is the principal amount ($1930)
• $r$ is the annual interest rate (4% or 0.04)
• $t$ is the time in years (8 years)

First, calculate the simple interest:

$\text{Simple Interest} = 1930 \times 0.04 \times 8 = 618.4$

Now, add the interest to the principal to find the total amount:

$\text{Total Amount} = P + \text{Simple Interest} = 1930 + 618.4 = 2548.4$

Benjamin receives $2548.40 after 8 years.

8. If Benjamin withdrew half of the investment after 4 years, how much would he have received after 8 years?

Tip: When dealing with simple interest, remember that the interest is calculated only on the principal amount, not on any accumulated interest.
