What will be the total cost of the cell phone plan for 6 months of use? a. 30 b. 90 c. 150 d. 165

According to the graph, the answer is C. 150

 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.
