Final answer:
After multiplying the 7 rows by 23 chairs per row to find the initial total and then subtracting the 6 chairs that were removed, there are 155 chairs left in the theater.
Step-by-step explanation:
The question asks us to calculate the total number of chairs left in a theater after some have been removed. Initially, the theater had 7 rows of 23 chairs each. To find the total number of chairs before any were removed, we multiply the number of rows by the number of chairs per row:
- Multiply the number of rows by the number of chairs per row: 7 rows × 23 chairs/row = 161 chairs.
- Subtract the number of chairs that were removed: 161 chairs - 6 chairs = 155 chairs left.
Therefore, after the workers removed 6 chairs from the theater, there are 155 chairs left.
