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

### Instruction:
Oprah has 3500 cars in her collection. If the average number of cars she gives away per year is 50, how many years will it take to reduce her car collection to 500?

### Response:
If Oprah wants to have 500 cars left, she will have to give away 3500-500 =<<3500-500=3000>>3000 cars.
If the average number of cars she gives away per year is 50, she will have to give away cars for 3000/50 = 60 years
