Answer:
D. The wages earned depends on the time worked.
Explanation:
We have been provided a graph and we are asked to determine the relationship between the given quantities on the graph.
Since we know that horizontal axis or x-axis represents independent variable and y-axis or vertical axis represents dependent variable.
We can see from our graph that time is given on x-axis. This means that time is independent variable.
We can also see from our graph that y-axis represents wages earned in dollars, so wages earned will be dependent variable. This means that wages earned by a person depends on the number of hours he worked.
If a man will increase his working hours, his wages will also increase. Similarly, if a man will decrease or reduce his working hours, his wages will also decrease.
Therefore, the wages earned depends on the time worked and option D is the correct choice.
