Below is an instruction that describes a task. Write a response that appropriately completes the request in English. Please answer in English.

### Instruction:
Mitzi brought $75 to the amusement park. She spent $30 on a ticket, $13 on food, and $23 on a T-shirt. How much money does she have left?

### Response:
Mitzi spent a total of $30 + $13 + $23 = $<<30+13+23=66>>66.
So she still has $75 - $66 = $<<75-66=9>>9 left.
