Solve the problem.The cost of manufacturing clocks is given by C(x) = 60 + 48x - x2. Also, it is known that in t hours the number of clocks that can be produced is given by x = 6t, where 
Express C as a function of t.
A. C(t) = 60 + 288t - 36t2 B. C(t) = 60 + 288t - 36t C. C(t) = 60 + 48t - 6 D. C(t) = 60 + 48t + t2
