A power plant is located on a river that is 750 feet wide. To lay a new cable from the plant to a location in a city 1 mile downstream on the opposite side costs $200 per foot across the river and $100 per foot along the land. Suppose that the cable goes from the plant to a point Q on the opposite side that is x feet from the point P directly opposite the plant. Write a function C(x) that gives the cost of laying the cable in terms of the



▸ C(x) = 200 + 100(5280 - x)

▸ C(x) = 200 + 100(1 - x)

▸ C(x) = 200(750 - x) + 100(1 - x)

▸ C(x) = 100 + 200(5280 - x)
