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

### Instruction:
 Tony anajaribu kunywa maji zaidi, kwa hivyo amekuwa akifuatilia kiasi cha maji anachokunywa. Jana, alikunywa onsi 48 za maji, ambayo ni 4% chini ya kile alichokunywa siku mbili zilizopita. Tony alikunywa maji kiasi gani siku mbili zilizopita?


### Response:
 Tony alikunywa jana 100% - 4% = 96% ya kile alichokunywa siku mbili zilizopita.
Acha x iwe kiasi cha maji Tony alikunywa siku mbili zilizopita.
Kwa kuwa 96% = 48 onsi, basi x = 48 / .96 = 50 onsi.
