Two Converging Lenses, the First with Focal Length $10.0 \mathrm{~cm}$ And the Second with Focal Length

Two converging lenses, the first with focal length $10.0 \mathrm{~cm}$ and the second with focal length $20.0 \mathrm{~cm}$ , are separated by $40.0 \mathrm{~cm}$ . An object, $3.00 \mathrm{~cm}$ in height, is placed $30.0 \mathrm{~cm}$ in front of the first lens. Where is the image formed by the first lens?

A) $15.0 \mathrm{~cm}$ after the second lens
B) $7.50 \mathrm{~cm}$ after the second lens
C) $15.0 \mathrm{~cm}$ after the first lens
D) $7.50 \mathrm{~cm}$ after the first lens
E) $55.0 \mathrm{~cm}$ after the second lens
