Final answer:
Hana's parents will deposit $350 in the account on her sixteenth birthday.
Step-by-step explanation:
To find out how much money will be deposited in the account on Hana's sixteenth birthday, we need to determine the amount her parents will add each year. Since they start with $50 and increase the amount by $25 each year, we can create a sequence to represent the deposits:
$50, $75, $100, $125, $150, ...
From this sequence, we can see that on her sixteenth birthday, they will deposit $175 in the account. Therefore, the correct answer is C) $350.
