Big Idea: Observation and description of changes in the world around us are the first steps in finding and learning about patterns.

Essential Question: How can I visually expalian situations where one thing changes based on another?


 * Problem 3.3 : Predicting Profits**


 * A: How much profit will be made if 10 customers go to the tour? 25 customers? 40 customers?**

The profit that would be made if 10 customers went on the tour would be about $150. For 25 customers the profit would be about $375. For 40 customers the profit would be about $600.


 * B: How many customers are needed for the partners to earn a $200 profit? A $500 profit? A $600 profit?**

To get a $200 profit the partners would need about 10-15 people. For a $500 profit they will need about 30-35 people. For a $600 profit they will need about 35-40 people.


 * C: How does the profit change as the number of customers increases? How is this pattern shown in the graph?**

The profit changes by the number of people that come, like in this situation the more people that come the more price will start to go up. In the graph the points start to go up because as the number of people go up so does the price.


 * D: If the tour operators reduced their expenses but kept the price at $350, how would this change the graph?**

On the graph the point would go striaght above the original just higher becasue they would make more profit.


 * Problem 3.3 Follow Up

1.** **In the profit graph, points at the intersection of two grid lines, such as (20, 300) and (40, 600) are easy to read. Use the "easy to read " points to figure out what the profit would be if only 1 customer went on the tour. How about 2 customers? 3 customers? 100 customers? Describe, in words, the estimated profit for any number of customers.**

Well the profit for 1 customer would be about $15. For 2 customers the profit would be about $30. For 3 customers the profit would be about $45. For 100 customers the profit would be about $1,500. You do all this all by multiplying the number of customers by 15.
