Are there any answer choices for the question?
Fist add 203 and 220 and you get 423.
Then add all the dvds 11+3 and you get 14 then
Next add all the video games 11+14 and you get 25
next divide 25 from 423 then you get 16.92
then divide the dvds 423 divided by 14 and you get 30.21
I'm pretty sure its the first chose but I'm not sure sorry i couldn't help more
