FARMERS MARKET
(Systems of Linear Equations – Slope-Intercept Form)
Lesson:
Engage students in the content.
A farmer wants to estimate the cost of transporting his produce to market. There are two
trucking companies that he can choose from to transport his produce. The Long Haul trucking
company charges \$10.00 per mile and a flat fee of \$1000. The Keep On trucking company
charges \$4.50 per mile and a flat fee of \$1500.
1.
For each trucking company, complete the tables that show the number of miles to market
(m) and the total cost of transporting the produce (T) if the markets are 10, 20, 30, 40, and
50 miles away. (CLG: 1.1.2)
2.
Enter your data into the list storage of your calculator. (CLG: 1.1.2)
Teacher Tip:
Discuss with students how to name their lists. This will help
them save their lists for many different activities, so they
can go back to them if they need to.
3.
Set up an appropriate graphing window, and then graph the data. (CLG: 1.1.2)
Teacher Tip:
Discuss with your students what makes an appropriate
window. Discuss the mathematics behind graphing data just
as if you were graphing it on paper. Discuss the domain of
the x values, and the range of the y values. Help students to
see the data points in different windows and understand the
need for an appropriate window.
4.
What type of relationship exists among the data points for each trucking company?
Teacher Tip:
Discuss with the students linear and non-linear relationships.
