Let T be the price of the table.
Let C be the price of one chair.
Kenny paid $3685 and received $185 change.
Therefore, the table and 5 chairs cost $3685 - $185 = $3500.
We also know that the table cost the same as 2 chairs.
T = 2C
T + 5C = $3500
Substitute:
2C + 5C = $3500
7C = $3500
Simplify:
C = $500
Hence, the cost of the table is $500 * 2 = $1000.
