Jude bought three chairs for his house, all at the same price. He also bought a table that costs $50 and two sets of plates at $20 for each set. After giving the cashier $130, Jude got a $4 change. How much did each of the chairs cost?
The two sets of plates amount to $20 x 2 = $

<output>40</output>
40.
So the table and the two sets of plates amount to $50 + $40 = $
<gadget id="calculator">50+40</gadget>
<output>90</output>
90 in all.
Since Jude received a $4 change, then he paid a total of $130 - $4 = $

<output>126</output>
126 for the chairs, tables, and plates.
Thus, the three chairs cost $126 - $90 = $
<gadget id="calculator">126-90</gadget>
<output>36</output>
36.
Therefore, each chair cost $36/3 = $
