Concept explainers
a.
To complete the given table.
a.
Explanation of Solution
Table:
Number of songs downloaded | Total cost($) | Total Cost/Number of Songs Downloaded |
2 | 4 | 2 |
4 | 8 | 2 |
6 | 12 | 2 |
Conclusion:
Hence the above table has been completed according to data.
b.
To explain how the cost changes with the number of increase of the songs downloaded.
b.
Explanation of Solution
Given:
Number of songs downloaded | Total cost($) | Total Cost/Number of Songs Downloaded |
2 | 4 | 2 |
4 | 8 | 2 |
6 | 12 | 2 |
Interpretation:
When the table is observed, it is clear that, when there is a increase in Number of songs downloaded, the total cost also increases.
Which means, if there is ‘ n’ times increment in the number of songs downloaded, there will be ‘ n’ times increment in the Total Cost.
Conclusion:
The above interpretation makes it clear that the Number of songs downloaded and Total Cost bear a linear relationship.
c.
To interpret the value of Total Cost divided by Number of songs downloaded.
c.
Explanation of Solution
Given:
Number of songs downloaded | Total cost($) | Total Cost/Number of Songs Downloaded |
2 | 4 | 2 |
4 | 8 | 2 |
6 | 12 | 2 |
Interpretation:
Here, When the table is observed, the value of total cost divided by total number of songs downloaded
is constant and equal to 2. This means, numerically the value of total cost will be twice the value
of number of songs downloaded.
