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

### Instruction:
 James paves a new parking lot. It is 400 feet by 500 feet. Only 80% of that is useable for parking. It takes 10 square feet to park a car. How many cars can be parked?


### Response:
 Er hat 400*500=<<400*500=200000>>200.000 Quadratfuß Parkplatz.
Es gibt 200.000*0,8=<<200000*0.8=160000>>160.000 Quadratfuß Parkfläche.
Das bedeutet, er kann 16.0000/10=16.000 Autos parken.
