Maybe it's Wells Fargo

That statement is incomplete; stated should also be:
"and leaves the account untouched"
(no withdrawals or other deposits and no interest".
The -126.13 is obviously an overdraft.
The 360 is obviously the net weekly deposit (x weeks).
So C) is obviously the correct choice.

As example, after 7 weeks:
y = account balance = 360*7 - 126.13

and no interest

That's already covered under "no … other deposits".

...or service charges...

That's already covered under "no withdrawals".

Maybe Henry works at Wells Fargo, and, based on legal advice, he opened this account to park his weekly commission kick…, er, um, ah, "paycheck".
