Answer 2

Answer:

$7.5

Step-by-step explanation:

The number lines show that the ratio of bottles of water to dollars is 4:10.

We are looking for a ratio that is equivalent to 4:10.

First let's find out how much one bottle costs by dividing both parts of the ratio by 4.

1 bottle of water costs $2.5. The ratio can be written as 1:2.5.

Now we can find how much 3 bottles cost by multiplying both parts of the ratio by 3.

So therefore 3 bottles cost $7.5
