2. An island is 10 mi from the nearest point on a straight shoreline; that point is 8 mi from a power station. A utility company plans to lay electrical cable underwater from the island to the shore and then underground along the shore to the power station. Assume that is costs $3000 per mile to lay cable underwater and $2000 per mile to lay underground cable. At what point should the underwater cable meet the shore to minimize the cost of the project. Note: be sure to check the endpoints of your interval of interest! island 10 power station 8
