read the following details.

to open a savings account at north bank, a customer must deposit at least $100 into the account.

to open a checking account at north bank, a customer must deposit at least $500 into the account.

gervais opened a savings account at north bank, but not a checking account.

which conclusion can be logically drawn based on these details?

gervais does not have $50.
gervais has at least $100.
gervais has banked at north bank before.
gervais does not need a checking account.

Gervais has at least $100.

Explanation: In the beginning of the question the first thing it says is that to open a savings account at North Bank, a customer must deposit at lease $100 into the account, which automatically takes away the first answer that Gervais does not have $50. There also is no evidence that Gervais has or has not banked at North Bank before, which takes away the second answer. Although the last answer may be true, Gervais need a checking account but does not have enough money; thus leaving only the first Gervais has at least $100, which is true and had evidence to back it up.

Hope this helps! :)
