Concept explainers
To sketch the step graph to represent the cost of going over the mileage.
Explanation of Solution
Given:
Cost per miles is $0.20 for each mile over 12,000. Any fraction of a mile is rounded up to the next mile.
Calculation for graph:
Create a table using the given data
Number of miles over 12,000 | Cost |
1 | 0.20(1) = 0.20 |
1.5 | 0.20(2) = 0.40 |
2 | 0.20(2) = 0.40 |
2.5 | 0.20(3) = 0.60 |
3 | 0.20(3)=0.60 |
At 12,00 miles, the cost is included in the rent. So, we have a open
Graph:
Conclusion:
Therefore, the graph is a step function representing the given data.
