Chapter 1.1, Problem 24PPSE

Solution

To Identify: The number of bottles of water requires according to the given data.

The number of bottles of water requires for $n$ students is $2n$ .

Given information:

  

Calculation:

Given, the graph is as follows:

  

Making a table for representing the given data:

Number of students	Process Column	Number of bottles of water
$1$	$2\left(1\right)$	$2$
$2$	$2\left(2\right)$	$4$
$3$	$2\left(3\right)$	$6$
$:$	$:$	$:$
$n$	$2\left(n\right)$	$2n$

So, the patter is: $\text{Number}\text{of}\text{bottles}\text{of}\text{water}=2\times \text{Number}\text{of}\text{students}$

Calculate the bottle for $n$ students:

  $\begin{array}{c}\text{Number}\text{of}\text{bottles}\text{of}\text{water}=2\times \text{Number}\text{of}\text{students}\\ =2\times n\\ =2n\end{array}$

Thus, $2n$ bottles required for $n$ students.
