UpStudy AI · Accepted Answer

To calculate the amount in the account after 3 years with simple interest, you can use the simple interest formula:

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

Where:
- $$ P $$ is the principal amount (\$1,000)
- $$ r $$ is the annual interest rate (4% or 0.04)
- $$ t $$ is the time in years (3 years)

**Step 1: Calculate the Simple Interest**

$$
\text{Simple Interest} = 1000 \times 0.04 \times 3 = 120
$$

**Step 2: Calculate the Total Amount in the Account**

$$
\text{Total Amount} = \text{Principal} + \text{Simple Interest} = 1000 + 120 = 1120
$$

So, the amount in the account at the end of the 3-year period is:

$$
\$1,120
$$
At the end of 3 years, Kristina has \$1,120 in the account.
