Solve the problem.A power plant is located on a river that is 650 feet wide. To lay a new cable from the plant to a location in a city 1 mile downstream on the opposite side costs $225 per foot across the river and $150 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) = 225
+ 150(1 - x)
B. C(x) = 225
+ 150(5280 - x)
C. C(x) = 225(650 - x) + 150(1 - x)
D. C(x) = 150
+ 225(5280 - x)
