Answer:
D. (80, 25)
Step-by-step explanation:
From the graph, the time and cost at which the two stores charge the same amount is the point where the two lines intersect.
• Tracing the point of intersection to the x-axis, the value of the time = 80.
,
• Similarly, tracing the same point to the y-axis, the value is between 20 and 30, approximately 25.
Therefore, the point that best estimates the time and cost at which the two stores charge the same amount is:
The correct option is D.
