How much more does the new camera cost than the old camera? ** The new camera cost 4000*.3=$<<4000*.3=1200>>1200 more than the old camera.
How much did the camera cost? ** So the camera cost 4000+1200=$<<4000+1200=5200>>5200
How much did the lens cost? ** The lens cost 400-200=$<<400-200=200>>200
How much did the camera and lens cost? ** So the total cost was 5200+200=$<<5200+200=5400>>5400
