To find the unit rate, you need to calculate how many bags of chips you get per dollar.
First, we know:
- Total cost = $56.04
- Total bags = 9
To find the cost per bag, we divide the total cost by the number of bags:
\[ \text{Cost per bag} = \frac{56.04}{9} \approx 6.227 \]
Now, to find the unit rate of bags per dollar, we take the reciprocal of the cost per bag:
\[ \text{Bags per dollar} = \frac{1}{\text{Cost per bag}} = \frac{1}{6.227} \approx 0.160 \]
So, the unit rate for bags of chips per dollar is approximately:
\[ 0.16 \text{ bags per dollar} \]
Thus, the final answer rounded to the nearest hundredth is:
\[ 0.16 \text{ bags per $} \]
