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

### Instruction:
There were 80 cars in a parking lot. At lunchtime, 13 cars left the parking lot but 5 more cars went in than left. How many cars are in the parking lot now?

### Response:
The number of cars leaving the parking lot is 13.
The number of cars entering the parking lot is 13 + 5 = <<13+5=18>>18.
So, the number of cars in the parking lot is 80 - 13 + 18 = <<80-13+18=85>>85.
#### 85
