Explanation:

Step1: Analyze the total change formula

The total change is calculated as the sum of the change on Monday ($-51.25$) and the change on Tuesday ($+39.50$), so we use the formula $-51.25 + 39.50$.

Step2: Perform the addition

To add these two numbers, we can think of it as $39.50 - 51.25$. Subtracting, we get $39.50 - 51.25 = -11.75$. Since the result is negative, it means the account balance decreased.
