Answer:
it cost $7 for each chair and $9 for each table
Explanation:
when 5 chairs and 6 tables were rented, the total cost was $53, which means that the 5 chairs cost $35 (5x$7) and the 6 tables cost $18 (6x$9). Similarly, when 3 chairs and 2 tables were rented, the total cost was $21, which means that the 3 chairs cost $21 (3x$7) and the 2 tables cost $12 (2x$9).
