Explanation of Solution
Given information :
Songs downloaded | Balance($) |
0 | 50 |
5 | 45 |
10 | 40 |
15 | 35 |
The table shows the balance on a $50 music card after a certain number of songs have been downloaded.
Graph :
Plot the horizontal axis song downloaded and the corresponding balance along vertical axis.
The graph is obtained as:
Interpretation : from the above graph it can be concluded that there is song downloaded and the corresponding balance along vertical axis.
b.
To find the balance on the card after 25 song downloaded.
