The problem asks for the total change in the All-Plus stock over two days, given:

1. On the first day, the change in value was $-\$2.50$.
2. On the second day, the value dropped $\frac{1}{4}$ of the change from the previous day.

Step-by-step solution:

1. Calculate the second day's change: The second day's change is $\frac{1}{4}$ of the first day's change: $\text{Second day's change} = \frac{1}{4} \times (-\$2.50)$ $\text{Second day's change} = -\$0.625$

2. Find the total change over the two days: The total change is the sum of the changes on both days: $\text{Total change} = (-\$2.50) + (-\$0.625)$ $\text{Total change} = -\$3.125$

3. Round to the nearest cent: The total change rounds to $-\$3.13$.

Final Answer:

The total change in the All-Plus stock is $-\$3.13$.
