Cab fares
The charge for a cab ride is determined by the length of travel.
Some companies also charge a basic, fixed amount. Below are
descriptions of fares of three competing cab companies:
|
|
| Quick Cabs: |
|
$0.25 per kilometer
+ $4 fixed charge |
|
| |
| Fast Cabs: |
|
$0.50 per kilometer
+ $1 fixed charge |
|
|
|
| Speedy Cabs: |
|
$0.75 per kilometer
no fixed charge |
|
| |
|
Show the three cab fares in various representations (correspondence rule, value table, graph).
|
|
|
Which cab company would you choose if you needed to travel a distance of 2 kilometers? 8 kilometers? 16 kilometers?
| |
| Is there a ride that would cost the same with two of the cab compamies?
| |
|
Suggest a new fare which would be cheaper than the other three for any length of travel.
