The total cost to rent 5 chairs and 3 tables is $29. The total cost to rent 7 chairs and 9 tables is $73. What is the cost to rent each chair and each table?

Answer 1

5c + 3t = 29

7c + 9t = 73

triple 1st equation and subtract 2nd equation from the triple to ge 3c = 14

10c +9t = 87

3c = 14

c = 14/3 = $4.67 to rent 1 chair

t = (29-5(14/3))/3 = (87-70)/9= $1.88 per table

rounded off to nearest penny
