Answer: The correct option is
(C) 150.
Step-by-step explanation: We are given to find the total cost of the cell phone plan for 6 months of use.
From the graph, we note that the number of months are plotted across the X axis and the corresponding cost of the cell phone is plotted across the Y axis.
Also, we note that for 6 months of use of cell phone, we will be considering the point where the x co-ordinate is 6.
The corresponding y co-ordinate for x co-ordinate 6 is 150.
Therefore, for 6 months of use of cell phone, the cost is $150 because (6, 150) is a point on the line graph.
Thus, the required total cost is $150.
Option (C) 150.
