How much does he have left in the bank

First, let's calculate how much money was deposited into his account. 
33 × $348 = $11,484

Now, let's add that to his original amount of money in his account. 
$11,484 + $1,618 = $13,102

Next, let's calculate how much money was withdrawn from the account. 
36 × $16 = $576

Now, you would subtract that from the account balance. 
$13,102 - $576 = $12,526

Then, you would add the deposit from his uncle to his account balance. 
$12,526 + $261 = $12,787

The last step would be to subtract the money for the bike. 
$12,787 - $190 = $12,597

Justin has $12,597 in his bank account. 

I hope this helps! (Sorry to post this so late, my computer died before I could finish.)
