A party rental company has chairs and tables for rent. The total cost to rent 4 chairs and 8 tables is $89 . The total cost to r
puteri [66]
Let C = cost to rent each chairLet T = cost to rent each table

 4C + 8T = 73
2C + 3T = 28 
Multiply the 2nd equation by (-2) and then add the equations together 

  4C + 8T = 73
-4C - 6T = -56
 2T = 17T = 17/2 = 8.5

 Plug this in to the 1st equation to solve for C
 4C + 8(17/2) = 73
4C + 68 = 73
4C = 5C = 5/4 = 1.25
 So the cost to rent each chair is $1.25 and the cost to rent each table is $8.50
