Answer 1

1. A) Ben
2. B) Huong's Withdrawal

Explanation:

You want to know whether a $25 deposit or a $40 withdrawal will result in a greater amount in bank accounts starting from the same amount. You want to know which transaction is the bigger change.

1. Ending balance

A deposit will increase the amount in the account, and a withdrawal will decrease it. The account with a $25 increase will have more money than the account decreased by $40, when they start with the same amount.

Ben's account has more money, choice A.

2. Change

The amount the account value changed with the $25 deposit is $25. The amount the account value changed with the $40 withdrawal is $40. The withdrawal causes a larger change in the balance.

Huong's withdrawal represents a bigger change.
