Power Line A power station is on one side of a river that is 3 4 mile wide, and a factory is 8 miles downstream on the other side of the river. It costs $ 24 per foot to run power lines over land and $ 30 per foot to run them under water. The project’s cost is $ 1 , 098 , 662.40 . Find the length x labeled in the figure.
