Chapter 4.7, Problem 46PPS

To determine

To Graph:

Draw a graph for the given situation.

Explanation of Solution

Given Information:

A local studio must have atleast 5 students enrolled in a class , or else the class will be cancelled.Once 10 students are enrolled, a second class is started.

Calculation:

Let

x -axis = Number of students

y -axis = Number of classes

First we draw a table :

Number of students (x)	Number of classes (y)
$0\le x<5$	0
$5\le x<10$	1
$10\le x<15$	2
$15\le x<20$	3

Now ,

If the number of students is between 5 and 9, then there will be one class. So, there is a closed circle at (5, 1) and an open circle at (10, 1). Connect these points with a line. Graph the rest of the data in the table similarly.
