A party rental company has chairs and tables for rent. The total cost to rent 5 chairs and 2 tables is $18. The total cost to rent 3 chairs and 8 tables is $55 . What is the cost to rent each chair and each table?
lets call the cost of chairs c and tables t
5c+2t=18
3c+8t=55
multiplying the 1st equation by 4, 20c+8t=72
subtracting the second equation, 17c=17-->c=1
Therefore a chair costs $1, and a table costs $6.50
5c + 2t = 18
3c + 8t = 55 Multiply top equation by -4
-20c - 8t = -72 add this to second equation
-17c = -17
c = 1.00 I will let you take it from here,,,,,,
