# Comparing Car Rentals

By Susan LoFranco on Apr 24, 2017

• Graph a simple ratio by connecting the origin to a point representing the ratio in the form of y/x

## Procedure

• With the student review vocabulary - Ratio, X-Axis, Y-Axis, Linear Equation,
• Review with students the following:  A car rental costs \$155.00 per day plus \$0.25 gas surcharge for every mile driven.
• Using the media of students choice, together write a linear equation to represent the cost of renting a car for one day.  (y = 155.00 + 0.25g) and then calulate the car rental costs if the driver went 100 miles, 200 miles, and 300 miles in one day.
• Graph the rental costs with the number of miles driven on the x axis and the total costs on the y axis.
• Using the How Much will it Cost to Rent a Car? Worksheet review the instructions with the student.
• Once the student is confident have him/her complete the task using the students media of choice.

## Variations

• The student will need to determine the number of miles between their hometown and Miami Florida.  This can be done with a Google search. Enter the words "directions from (hometown) to Miami Florida" into the Google search box and the results should appear.
