Solution Steps

To determine the total number of chairs Andre sets up, we need to multiply the number of rows by the number of chairs per row.

Solution Approach
  1. Identify the number of rows and the number of chairs per row.
  2. Multiply these two numbers to get the total number of chairs.
Step 1: Identify the Variables

Let \( r = 4 \) (number of rows) and \( c = 7 \) (number of chairs per row).

Step 2: Calculate Total Chairs

The total number of chairs \( T \) can be calculated using the equation: \[ T = r \times c \] Substituting the values: \[ T = 4 \times 7 \]

Step 3: Perform the Calculation

Calculating the product: \[ T = 28 \]

Final Answer

The total number of chairs set up by Andre is \\(\boxed{28}\\).
