A media company is going to install cable from a house to

their connection box B. The house is located at one end

of a driveway 7 miles back from a road (see diagram).

The connection box is 25 miles down the road. The

cost of installing the cable is $656 per mile off the road and

$375 per mile along the road.

Let x be the distance from where the driveway meets the road to where the cable aving triublcomes to the road.

im just having trouble figuring out finding the minimum cost
