1. The problem states that Quinn has a 4-pint bottle filled with cider and wants to know how many times he can fill a 2-cup mug from it. 2. We know the conversion: 1 pint = 2 cups. 3. First, convert the bottle's capacity from pints to cups: $$4 \text{ pints} \times 2 \frac{\text{cups}}{\text{pint}} = 8 \text{ cups}$$ 4. To find how many times Quinn can fill the 2-cup mug, divide the total cups in the bottle by the mug's capacity: $$\frac{8 \text{ cups}}{2 \text{ cups}} = 4$$ 5. Therefore, Quinn can fill his 2-cup mug 4 times from the 4-pint bottle. Final answer: 4 times.
