- A. With each monthly deposit, the amount in Hana's bank account increased by $25.
- B. Before Hana made any monthly deposits, the amount in her bank account was $25.

Explanation
Choice A is correct. It's given that t represents the number of monthly deposits. In the given function f (t) = 100 + 25t , the coefficient of t is 25. This means that for every increase in the value of t by 1, the value of f increases by 25. It follows that with each monthly deposit, the amount in Hana's bank account increased by $25.
