Hello, I am confused with this problem .

A cable runs along the wall from C to P at a cost of $7 per meter, and straight from P to M at a cast of $25 per meter. Let x be the distance from C to P. If M is 48 meters from the nearest point A on the wall where P lies, and A is 106 meters from C, nd it such that the cost of installing the cable is minimized and nd this cost. 106 r C X p A 48 The cast is minimized when x is meters
