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

### Instruction:
 大瓶芒果汁容量为30盎司，每瓶售价2700比塞塔。小瓶容量为6盎司，每瓶售价600比塞塔。购买大瓶而不是等量的小瓶可以节省多少比塞塔？


### Response:
 等价关系：30盎司 = 240毫升
6盎司 = 48毫升
240/48 = 5
5瓶小瓶 = 3000比塞塔
3000 - 2700 = 300比塞塔
购买大瓶而不是等量的小瓶可以节省300比塞塔。
