1. **State the problem:** We have a bedroom width on a blueprint of 5.5 inches. The scale is 0.50 inches = 1 foot. We need to find the actual width of the bedroom in feet. 2. **Formula and explanation:** The scale means every 0.50 inches on the blueprint corresponds to 1 foot in real life. To find the actual width, use the formula: $$\text{Actual width} = \frac{\text{Blueprint width}}{\text{Scale width per foot}}$$ 3. **Calculate the actual width:** $$\text{Actual width} = \frac{5.5}{0.50} = 11$$ 4. **Interpretation:** The actual width of the bedroom is 11 feet. **Final answer:** 11 feet (Option A)
