# No idea how to solve this algebra problem!

The school cafeteria got rid of some old tables and bought new ones.  Old tables were 2x6, new tables are 2x8.

there are now 24 new tables in the cafeteria.  If the cafeteria has the same table area as before, how many old tables were removed?

I would have found it simple if they completely replaced the old tables with new tables.  However, my understanding of this question was that they got rid of SOME of the old tables.  They did not say they got rid of ALL.  So I interpreted the question to mean that they kept a combination of 24 new tables and some of the old tables.  ???????

Using the ratio of areas 16:12 per table, i found that there are 24 old and 24 new, with a total area of 672.  This means the original number of old tables was 56, but they are only keeping 24, therefore they have to remove 32 old tables.  I have no real idea what I did...it seems crazy.
