Question
A phone company charges P39 for the first 10 minutes of an international long distance phone call and P 12 per minute after that. Find the cost function C(X) as a function of the length of phone call in X minutes. 39 C(x) = if 0<x<10 12x-81 if x> 10 A 12 C(x)% = if 0<x<10 12 + (39x- 120) if x> 10 39 C(x) =D if xs 10 39+(12x-1) if x> 10
