Answer:
Anna's account has the greatest change.
Explanation:
Karla, Ruby, Anna, and Megan each had a balance of $0 in her bank account on the first day of April.
2nd day balances:
Karla: $43
Ruby: -$25
Anna: -$48
Megan: $42
We can see that Anna had the greatest negative changes. Means out of zero, she spent $48 more.
Rest changes, either positive or negative, are lesser than Anna.
