Question

A party rental company has chairs and tables for rent. The total cost to rent 3
chairs and 8 tables is $55. The total cost to rent 5 chairs and 2 tables is $18. What is the cost to rent each chair and each table

Answer 1

Answer:

• chair: $1.00
• table: $6.50

Step-by-step explanation:

When you have a non-trivial number of sets of equations to solve, it can be useful to let a machine solve them for you. Here, suitable equations for chair cost (c) and table cost (t) can be written as ...

• 3c+8t = 55
• 5c+2t = 18

___

I find a graphing calculator easy to use for solving such equations.

___

A spreadsheet programmed with Cramer's Rule can do it, too. The second attachment shows the spreadsheet formulas used to solve the standard-form linear equations of the kind that can be written for this problem. The third attachment shows the solution(s).
