Congratulations! The MARS (Midway Amusement Rides) Company has just hired you to design bumper-car rides.
As a bumper-car designer there a few things you need to know. First, bumper-car rides are a very popular ride at amusement parks and carnivals. Second, bumper cars ride on a smooth surface with bumper rails all round it. MARS makes their bumper-car floors from 1 meter-by-1 meter square tiles (area). The bumper rails are built from 1-meter sections of railing (perimeter).
The other bumper-car designers at MARS are excited to have you help them solve some of their problems. Use the tiles to help you design the bumper car rides. Experiment with the tiles. Sketch your design(s) on the graph paper and record you dimensions on the tables. Be sure to calculate the area and the perimeter of each design.

Problem 1: |
Badger State Shows in Wisconsin requests a rectangular bumper-car ride with 36-square meters of floor space (area) and 26 rails (perimeter). Create and sketch one design that would meet their requirements. Record the length and width on the table.
|
Problem 2: |
Lone Star Carnivals in Texas wants a rectangular bumper-car ride with 36-square meters of floor space (area) and lots of rails (perimeter). Create and sketch three designs that would offer more rails that your design for the Badger State Shows. Record the dimensions on the table. Which design would you recommend? Highlight that design.
|
Now it is time to prepare a cost estimate for each of the companies. MARS charges $25 for each rail section and $30 for each floor tile.
Problem 3: |
Calculate the cost of your design for Badger State Shows. Record this information on the table.
|
Problem 4: |
Calculate the cost of each of your three designs for the Lone Star Carnival. Record this information on the table.
|
Problem 5: |
Write an expression that could be used for calculating costs. Let A equal area (number of tiles). Let P equal perimeter (number of rails).
