Answer:
C(t)= 0.5kg* (2/3) ^ t
Step-by-step explanation:
The water purifier will filter 1/3 of the current contaminants each hour. In other words, it will reduce the contaminant into 2/3 of it current mass. If the contaminant 1 kg, after 1 hour will be 2/3 kg, then become 4/9 kg after 2 hours. You have to multiply the contaminant with 2/3 every hour.
The equation will be
C(t)= X * (2/3) ^ t
C(t)= 0.5* (2/3) ^ t
