Locate the point P that will result in a minimum cost. Solve for x.

In the following diagram S represents the position of a power relay station located on a straig straight coast and E shows the location of a marine biology experimental station on an island . A cable is to be laid connecting the relay station with the experimental station . I If the cost of running the cable on land is $1 50 / running foot and the cost of running the cable under water is $2 30 / running foot , locate the point P that will result in a minimum cost ( solve for x ) .
