Solve the problem.The cost of manufacturing clocks is given by C(x) = 70 + 48x - x2. Also, it is known that in t hours the number of clocks that can be produced is given by x = 7t, where 
Express C as a function of t.
A. C(t) = 70 + 48t - 7 B. C(t) = 70 + 336t - 49t C. C(t) = 70 + 48t + t2 D. C(t) = 70 + 336t - 49t2
