Answer 1

Answer:

Cost of 3 bottles will be $7.5.

Step-by-step 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 = $\frac{10}{4}=\ 2.5$

So we can say that;

Cost of n bottles = $\ 2.5n$

Cost of 3 bottles = $\ 2.5\times 3 = \ 7.5$

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
