Solve the problem.A power plant is located on a river that is 700 feet wide. To lay a new cable from the plant to a location in a city 2 miles downstream on the opposite side costs $200 per foot across the river and $125 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 
A. C(x) = 200
+ 125(2 - x)
B. C(x) = 125
+ 200(10,560 - x)
C. C(x) = 200
+ 125(10,560 - x)
D. C(x) = 200(700 - x) + 125(2 - x)
