Quiz 2 Problem The double number line shows that 444 bottles of water cost 101010 dollars at a music festival. Based on the ratio shown in the double number line, how much does 333 bottles of water cost? dollars Report a problem

Answer 1

$7.5 Dollars

Explanation:

The cost of 4 bottles is $10. So, 1 bottle is going to be $2.50.

Now, to find the cost of 3 water-bottles, we have to multiply.

$2.50 * 3 = $7.50.

So, the answer to this question is 3 bottles = $7.50

(Hope this helps!)

Answer 2

Cost of 3 bottles will be $7.5.

Explanation:

Given:

According to double number line.

Cost of 4 bottles = $10

Based on this we need to find the cost of 3 bottles of water.

Solution:

Now we know that;

4 bottles = $10

1 bottle = Cost of 1 bottle

By using Unitary method we get;

Cost of 1 bottle =
`(10)/(4)=\$2.5`

So we can say that;

Cost of n bottles =
`\$2.5n`

Cost of 3 bottles =
`\$2.5* 3 = \$7.5`

Hence Cost of 3 bottles will be $7.5.

Now we have drawn the double number line.

Bottom line(Line 1) will be number of bottles:

1 2 3 4 5 6

Top line (Line 2) will be the cost of corresponding bottles:

2.5 5 7.5 10 12.5 15
