So, the Mystic Aquarium needs 4 + 2 + 20 = 26 buckets of fish each day. Thus in a week, it needs 26 x 7 = 182 buckets of fish. Therefore, 546 buckets of fish will last for 546 / 182 = 3 weeks. So the final answer is 3. <ibo> A na-enye dolphins nri 4 / 2 = 2 bọketị azụ kwa ụbọchị. A na-enye ụmụ anụmanụ ndị bi n'oké osimiri nri 4 x 5 = bọket 20 nke azụ kwa ụbọchị. Ya mere, Ụlọ Mmiri Mystic chọrọ 4 + 2 + 20 = bọket 26 nke azụ kwa ụbọchị. N'ihi ya, n'otu izu, ọ chọrọ ite azụ̀ 26 x 7 = 182. Ya mere, bọket 546 ga-ezu maka izu 546 / 182 = izu 3.
