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
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
