Cost of Laying Cable In the following diagram, S represents the position of a power relay station located on a straight coastal highway, and M 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. If the cost of running the cable on land is $3/running foot and the cost of running cable under water is $5/running foot, find an expression in terms of x that gives the total cost for laying the cable. What is the total cost when x = 2500? When x = 3000?
