To calculate the interest charged at the end of the first month, you can use the formula:
\[ \text{Interest} = \text{Principal} \times \text{Rate} \]
In this case:
- Principal = $477.95
- Rate = 1.5% = 0.015
Now, plug in the numbers:
\[ \text{Interest} = 477.95 \times 0.015 = 7.16925 \]
Rounding to two decimal places, the interest charged at the end of the first month would be approximately $7.17.
Therefore, the correct answer is $7.17.
