You know that the scale used in the model is:
[tex]3in=80ft[/tex]And the height of the bridge is:
[tex]213ft[/tex]Let be "x" the height (in inches) of the model of the George Washington Bridge.
Using the data provided on the exercise, you can set up the following proportion:
[tex]\frac{3}{80}=\frac{x}{213}[/tex]Solving for "x", you get:
[tex]\begin{gathered} \frac{3}{80}\cdot213=x \\ \\ \frac{639}{80}=x \\ \\ x\approx7.99 \end{gathered}[/tex]Therefore, the answer is:
[tex]7.99\text{ }inches[/tex]
