A grocery store sells 6 bottles of water for $4 and 18 bottles of water for $10. Is the cost of the water proportional to the number sold? EXPLAIN.

Answers

Answer 1

Answer:

The answer is "No", the cost of water is not proportional to the number of sold.

What is the ratio?

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.

Mr. Richard's class is holding a canned food drive for charity. Juliet collected 10 more cans than Rosana. Santiago collected twice as many cans as Juliet. If they collected 130 cans altogether, how many cans did Juliet collect?

Answers

if we represent the number of cans Juliet collected as J we can express Rosanna's number as J - 10 and Santiago as 2J so all their cans together is J + 2J + J - 10=130. 4J = 140 and J = 35.
