A cable runs along the wall from C to P at a cost of $3 per meter, and straight from P to M at a cost of $5 per meter. Let x be the distance from C to P. If M is 8 meters from the nearest point A on the wall where P lies, and A is 18 meters from Ç, find x The minimum installation cost is $. such that the cost of installing the cable is minimized and find this cost. The cost is minimized when x is meters. 18 A M
