Final answer:
To find the width difference between George Washington's mouth and his eye on Adela's mural, we need to determine the actual dimensions of the mouth and the eye on Mount Rushmore, using the given scale. We then subtract the actual width of the eye from the actual width of the mouth to find the difference.
Step-by-step explanation:
To find the width difference between George Washington's mouth and his eye on Adela's mural, we need to determine the actual dimensions of the mouth and the eye on Mount Rushmore. Adela's mural uses a scale of 6 ft to 1 ft, so we need to convert the measurements from the mural scale to the actual scale. Let's say the width of George Washington's mouth in the mural is x feet. According to the scale, the actual width of his mouth would be 6x feet. Similarly, let's say the width of his eye in the mural is y feet. According to the scale, the actual width of his eye would be 6y feet. Therefore, the difference in width between his mouth and his eye on Adela's mural would be 6x - 6y feet.
