The answer is "No", the cost of water is not proportional to the number of sold.
The ratio notion is used in mathematics when evaluating two or more numbers. It works as a comparison tool to demonstrate how big or small a particular number is. A ratio divides two quantities to compare them.
As per the given information in the question,
The cost of 6 bottles of water is $4.
Then, the price of each bottle will be,
= $4/6 = $0.66
The next condition is,
The cost of 18 bottles of water is $10
Then, the price of each bottle will be,
= $10/18 = $0.55
Comparing both the values, the ratio is not the same.
