Calculate the cost per chair
To find the cost of one chair, divide the total cost of the chairs Mr. Evans bought by the number of chairs.
The total cost for Mr. Evans is $384 for 4 chairs.
$$ \text{Cost per chair} = \frac{384}{4} = 96 $$

Calculate the total cost for Mr. Martin's chairs
Now, multiply the cost per chair by the number of chairs Mr. Martin bought (9 chairs).
The cost per chair we just found is $96.
$$ \text{Total cost for Mr. Martin} = 9 \times 96 $$
- Perform the multiplication Now, calculate the total cost for Mr. Martin's 9 chairs.
$$ 9 \times 96 = 864 $$
Mr. Martin paid $864 for the chairs.
