I can’t see the graph you mention. Please either upload the graph image or give two clear points from it (for example the bill at two different minute values).
How I’ll solve it once I have that:
1. Use two points (x1, y1) and (x2, y2) from the graph to find the rate (slope) m = (y2 − y1)/(x2 − x1).
2. Find the fixed monthly charge (y-intercept) b by solving b = y1 − m·x1.
3. Evaluate the cost at 35 minutes: cost = m·35 + b.
If you post the graph or two points, I’ll calculate which answer (A–D) is correct.
