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

### Instruction:
A store owner repacked his oils into 200 mL bottles. He was able to make 20 bottles. How many liters of oil did the store owner have?

### Response:
 Chupa 20 za mafuta ni sawa na 200 mL x 20 = <<20*200=4000>>4000 mL.
Kwa kuwa 1 lita ni sawa na 1000 mL, basi mmiliki wa duka alikuwa na awali 4000/1000 = <<4000/1000=4>>4 lita za mafuta.
