Chapter 1.1, Problem 22PPSE

Solution

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

The number of bottles of water requires for $5$ students is $10$ .

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: $Numberofbottlesofwater=2\times Numberofstudents$

Calculate the bottle for $5$ students:

  $\begin{array}{c}Numberofbottlesofwater=2\times Numberofstudents\\ =2\times 5\\ =10\end{array}$

Thus, $10$ bottles required for $5$ students.
