Step-by-step explanation:

Answer 2

24 bottles of water for $3 is better by $0.015

Step-by-step explanation:

Case 1:

Cost of 24 bottles = $3

Cost of 1 bottle =$\frac{3}{24}=0.125$

Case 2:

Cost of 36 bottles = $4

Cost of 1 bottle = $\frac{4}{36}=0.11$

24 bottles of water for $3 is better by amount = 0.125-0.11=0.015

Hence 24 bottles of water for $3 is better by $0.015
