it finally clicked for me when JY said "all the cans were recycled but only 50% of the material survived" !!! I get it now. it makes much more sense now that we are assuming that all the aluminum is recovered when recycled. for real if this is only a 3/5 difficulty level then my lord I got some work cut out

yes! I live in the Bay Area and I would love someone to talk to about the LSAT!
