Can it be solved by model?
Not really sure.I've seen this type of qn quite a number of times.I can't make sense with model.The 120 chairs & tables info gives a hint to use algebra because without it,algebra would not work.I think there are others who could do model for this qn particularly..Sorry..
Thank you for your great effort.
Sure no problem. ;)
