To determine which option saves more money when buying 36 oranges, we need to look at the prices associated with that quantity for both options.
In the provided points:
- For Option A at 36 oranges, the price is 15 dollars (point (36, 15)).
- For Option B at 36 oranges, we don't have a direct point listed, but we can infer from the points given that the price for 36 oranges would likely be higher than the last price provided (27 oranges at 18 dollars), indicating it could be more than 18 dollars.
Since Option A charges 15 dollars for 36 oranges and Option B charges more than 18 dollars, Option A is clearly the cheaper choice.
Thus, the correct answer is: Option A, because the price is lower for the same number of oranges.
