7-76.

A hotel in Las Vegas is famous for its large-scale model of the Eiffel Tower. The model, built to scale, is $128$ meters tall and $41$ meters wide at its base. If the real tower is $324$ meters tall, how wide is the base of the real Eiffel Tower?

Sketch the situation.

Use a proportional equation to find the height of the real tower. Set $x$ to the height of the original tower.
