Answer: $30

Step-by-step explanation: To solve this problem, we are just adding positive 45 to -15. If we add positive 15 to negative 15, we end up at zero and have to subtract 15 from 45 which gives us 30. Now, we have to add 30 from zero and we get 30.

Therefore, Tony now has $30 in his bank account
