Question

I will mark plus 25 pts. A party rental company has chairs and tables for rent. The total cost to rent 8 chairs and 4 tables is $ 45 . The total cost to rent 3 chairs and 2 tables is $ 21 . What is the cost to rent each chair and each table?

Answer 1

Let C= cost to rent each chair

Let T= cost to rent each table

8C + 4T = 45

3C + 2T = 21

Multiply the 2nd equation by (-2) and then add the equations together

8C + 4T = 45

-6C - 4T = -42

2C = 3

C = 3/2 = 1.5

Plug this in to the 1st equation to solve for T

8C + 4(3/2) = 45

8C + 6 = 45

8C = 39

C = 36/8 = 4. 5

So the cost to rent each chair is $1.50 and the cost to rent each table is $4.50

Hope this helped ‘cuz it took me forever! :)
