A party rental company has chairs and tables for rent. The total cost to rent 2 chairs and 6 tables is $40. The total cost to rent 5 chairs and 3 tables is $25.

What Is the cost to rent each chair and each table?

1 answer

Let's denote the cost to rent one chair as \( C \) and the cost to rent one table as \( T \).

From the information given in the problem, we can set up the following system of equations based on the rentals:

  1. Renting 2 chairs and 6 tables costs $40: \[ 2C + 6T = 40 \]

  2. Renting 5 chairs and 3 tables costs $25: \[ 5C + 3T = 25 \]

Now, we can solve this system of equations.

Step 1: Let's simplify the first equation. We can divide the entire equation by 2: \[ C + 3T = 20 \quad \text{(Equation 1)} \]

Step 2: Now we have:

  1. \( C + 3T = 20 \) (Equation 1)
  2. \( 5C + 3T = 25 \) (Equation 2)

Step 3: We can eliminate \( T \) by subtracting Equation 1 from Equation 2: \[ (5C + 3T) - (C + 3T) = 25 - 20 \] This simplifies to: \[ 4C = 5 \] Now, we can solve for \( C \): \[ C = \frac{5}{4} = 1.25 \]

Step 4: Now that we have the value of \( C \), we can substitute it back into Equation 1 to find \( T \): \[ 1.25 + 3T = 20 \] Subtract \( 1.25 \) from both sides: \[ 3T = 20 - 1.25 \] \[ 3T = 18.75 \] Now, divide by 3: \[ T = \frac{18.75}{3} = 6.25 \]

Thus, the cost to rent each chair and each table is:

  • Cost of each chair \( C = 1.25 \) dollars
  • Cost of each table \( T = 6.25 \) dollars

In conclusion:

  • Cost of each chair = $1.25
  • Cost of each table = $6.25
