Samuel has $58.23 in his bank account. He withdraws $39.78. How much is in his bank account now?

To find how much is left in his bank account, subtract the amount he withdrew from the total amount:

$58.23 - $39.78 = $<<58.23-39.78=18.45>>18.45. Answer: \boxed{18.45}.

To find out how much money is left in Samuel's bank account after the withdrawal, you need to subtract the amount he withdrew from the initial balance of his account.

Starting with $58.23 and subtracting $39.78, we can calculate the new balance as follows:

$58.23 - $39.78 = $18.45

Therefore, Samuel has $18.45 remaining in his bank account.
