Answer:
(B)the amount earned is a function of the number of hours worked.
Step-by-step explanation:
Let the time worked (in hours) worked =t
Let the amount earned =A
From the graph
When t=1, A= $10
When t=2, A= $20
When t=3, A= $30
When t=4, A= $40
When t=5, A= $50
We observe that as t increases, the amount increases.
We can, therefore, conclude that the amount earned is a function of the number of hours worked.
