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

### Instruction:
 Bwana Johnson ana dawa ya kutosha kwa siku 30. Baada ya sehemu nne tano ya siku, ana vidonge 12 vilivyobaki. Bwana Johnson anapaswa kumeza vidonge mangapi kwa siku ikiwa anachukua kipimo kile kile kila siku?


### Response:
 Bwana Johnson amekuwa akimeza vidonge kwa siku 30 * 4 / 5 = <<30*4/5=24>>24.
Ana siku 30 - 24 = <<30-24=6>>6 zilizobaki kumaliza vidonge.
Hivyo, anapaswa kumeza vidonge 12 / 6 = <<12/6=2>>2 kwa siku.
