How much did the two sets of plates cost? ** The two sets of plates amount to $20 x 2 = $<<20*2=40>>40.
How much did the table and the two sets of plates cost? ** So the table and the two sets of plates amount to $50 + $40 = $<<50+40=90>>90 in all.
How much did the chairs, tables, and plates cost? ** Since Jude received a $4 change, then he paid a total of $130 - $4 = $<<130-4=126>>126 for the chairs, tables, and plates.
How much did the three chairs cost? ** Thus, the three chairs cost $126 - $90 = $<<126-90=36>>36.
How much did each chair cost? ** Therefore, each chair cost $36/3 = $<<36/3=12>>12.
