Final answer:
To find the model's height, divide the actual height of the Washington Monument by the scale factor. The closest measurement for the monument's model, using a scale where 1 inch equals 15 feet, is 37 inches.
Step-by-step explanation:
To find the closest measurement for the model of the Washington Monument, apply the given scale factor. Since 1 inch represents 15 feet, we divide the actual height of the monument by the scale factor:
Actual height of Washington Monument = 555 feet
Scale factor = 1 inch / 15 feet
Height of model = Actual height / Scale factor
= 555 feet / (1 inch / 15 feet)
= 555 / 15
= 37 inches
Therefore, the closest measurement is 37 inches, which corresponds to choice 1.
