Answer:
34.65
Step-by-step explanation:
The value of the investment at the end of the month can be calculated by subtracting the loss from the initial value.
So, if the initial value was $48.45 and the loss was $13.80, then the value at the end of the month would be:
48.45−13.80=34.65
So, the value of the investment at the end of the month was $34.65.
