Two converging lenses, separated by a distance of 50.0 cm, are used in combination. The first lens, located to the left, has a focal length of 15.0 cm. The second lens, located to the right, has a focal length of 12.0 cm. An object, 3.00 cm high, is placed at a distance of 20.0 cm in front of the first lens. 

(a) Find the intermediate and final image distances relative to the corresponding lenses.

(b) What is the overall magnification? 

(c) What is the height of the final image?
