Respuesta :
D because
Helen= 330 + 30x because she started with $330 and each week deposited $30.
Vince= 50x because he started with no money and each week deposited $50.
The question asks for when Helen>Vince so the answer has to be D.
An inequality that represents the amount of money in Helen’s account was greater than the amount of money in Vince’s account :
50x < 330 + 30x
What is inequality?
"Inequality is mathematical expressions in which both sides are not equal."
For given situation:
the initial balance in Helen's account = $330
the initial balance in  Vince's account = $0
Helen deposited $30 into her account each week for x weeks.
This means, after x weeks, the amount of money in Helen's account would be, 330 + 30x
Also, Vince deposited $50 into his account each week for x weeks.
So, the amount of money in Vince's account would be,
0 + 50x = 50x
An inequality to represent the amount of money in Helen’s account was greater than the amount of money in Vince’s account would be,
330+ 30x > 50x
⇒ 50x < 330 + 30x
Therefore, the correct answer is option (D) 50x < 330 + 30x
