To calculate the interest earned on a savings account at the end of the month, you can use the formula for simple interest:
\[ \text{Interest} = \text{Principal} \times \text{Rate} \]
Where:
- Principal = $1,000.00
- Rate = 5.25% (or 0.0525 in decimal form)
Now, plug in the values:
\[ \text{Interest} = 1000 \times 0.0525 = 52.50 \]
So, at the end of the month, you should earn $52.50 in interest.
