Jerry has a bunch of folding card tables. He is trying to plan how he will set up the table seating for a big meeting. He likes the idea of people working in 3’s but doesn’t have enough tables to use only tables of 3. Using all his tables, he can seat everyone if he seats 3 people at a third of the tables and 4 people at the rest of the tables. He also likes the idea of groups all being the same size. If he uses all groups of 4, he can seat everyone with 2 tables left unused. How many tables does Jerry have and how many people is he expecting at the meeting?
