Solve the problem.A cable TV company charges $25 for the basic service plus $8 for each movie channel. Let C(x) be the function representing the total cost in dollars of subscribing to cable TV, using x movie channels. (a) Find the function C(x). (b) Suppose the cost per movie channel doubles. Write the resulting cost function D in terms of C.
A. (a) C(x) = 8x - 25
(b) D(x) = 2C(x)
B. (a) C(x) = 8x + 25
(b) D(x) = 2C(x)
C. (a) C(x) = 8x + 25
(b) D(x) = C(2x)
D. (a) C(x) = 25x + 8
(b) D(x) = C(2x)
