Exercise 47 Page 154

When creating a graph to describe a situation, our first step is to assign variables. In this case, we have two items that we are counting.

1. Number of Performances
2. Number of Pre-sale Ticket Requests

   Since the number of performances depends on the number of requests, let's make a table of values using ticket requests as our x -values.

   Ticket Requests	Performances
   0-249	0
   250-499	1
   500-749	2
   750-999	3
   1000-1250	4

   Let's graph those steps using the multiples of 250 as our end points. The first part of each step be a point, the last a circle.
