2. Investigation 3: Analyzing
Graphs and Tables
Using tables, graphs, and words to represent
relationships is an important part of algebra.
3. ∗ Coming up with the idea for Ocean and History Bike Tours
was only the first step for the five friends in starting their
business. They have other important plans to make as well.
Many of these plans involve questions about money.
What will it cost to
operate the tours?
How much should
customers be
charged?
What profit will be
left when all the bills
are paid?

5. 3.1 Renting Bicycles
The tour operators decided to rent bicycles
for their customers rather than having
customers bring their own bikes. They
called two bike shops and asked for
estimates of rental fees.
7. Problem 3.1
A. Which bike shop should Ocean and
History Bike Tours use? Explain your
choice.
B. Explain how you used the
information in the table and the graph
to make your decision.
9. Warm-up: Tuesday
Use the information from yesterdays investigation 3.1 to
answer the following questions:
1.What are the two variables?
2.Was it difficult to compare the prices of the two companies?
Why or why not?
3.On her way from home to the grocery store, a 6 mile trip,
Jessica stopped at a gas station to buy gas. After filling her

home after shopping. Sketch a graph to show the distance
Jessica traveled compared to time.

11. 3.2 Finding
Customers
Sidney, Liz, Celia, Malcolm, and
Theo had a route planned and a
bike shop chosen. Now they
needed customers. They had
to figure out what price to
charge so they could attract
customers and make a profit.
To help set a price, the partners did
some market research. They
obtained a list of people who had
taken other bicycle tours and asked
100 of them which of the following
amounts they would be willing to
pay for the Ocean and History Bike
Tour: $150, $200, $250, $300, $350,
$400, $450, $500, $550, $600.

• Problem 3.3 follow up
17. 3.3 Predicting Profit
Based on the results of their survey, the tour operators
decided to charge $350 per person for the tour. Of
course, not all of this money would be profit. To
estimate their profit, they had to consider the expenses
involved in running the tour. Sidney estimated these
expenses and calculated the expected profit for various
numbers of customers. She made a graph to present
her predictions to her partners. Since the profit
depends on the number of tour customers, she put the
number of customers on the x- axis.
