To calculate how much Annika will pay back after borrowing $2000 at an interest rate of 3.5% for one year, you can use the formula for simple interest:
\[ \text{Total Amount to Repay} = \text{Principal} + \text{Interest} \]
First, calculate the interest:
\[ \text{Interest} = \text{Principal} \times \text{Rate} \times \text{Time} \]
Where:
- Principal = $2000
- Rate = 3.5% = 0.035
- Time = 1 year
Now, plug in the values:
\[ \text{Interest} = 2000 \times 0.035 \times 1 = 2000 \times 0.035 = 70 \]
Now, calculate the total amount to repay:
\[ \text{Total Amount to Repay} = 2000 + 70 = 2070 \]
Thus, Annika will pay back $2,070 after one year. The correct response is:
$2,070
