the double number line shows that 4 bottles of water cost 10 dollars at a music festival. based on the ratio shown in the double number line, how much does 3 bottles of water cost? dollars

Answer

Explanation:

Step1: Find cost per bottle

First, find the cost of 1 bottle. We know 4 bottles cost 10 dollars. So the cost per - bottle $c$ is $c=\frac{10}{4}=\frac{5}{2}$ dollars.

Step2: Calculate cost of 3 bottles

Then, to find the cost of 3 bottles, multiply the cost per - bottle by 3. The cost of 3 bottles $C = 3\times\frac{5}{2}=\frac{15}{2}=7.5$ dollars.

Answer:

$7.5$
