The equation you provided is \( y = 10.2x \), where \( y \) is the total cost in dollars and \( x \) is the number of burgers.
This equation indicates that for each burger purchased, the cost increases by $10.2. Therefore, the unit rate, which represents the cost per burger, is:
\[
\text{Unit rate} = \frac{\text{Total cost}}{\text{Number of burgers}} = \frac{y}{x} = 10.2
\]
Thus, the unit rate is:
\(\$10.2 \text{ per burger}\).
So the correct answer is **$10.2 / burger**.
