To find the unit rate of dollars per bag of chips, you divide the total cost by the number of bags.
- Total cost: $56.04
- Number of bags: 9
Now, calculate the unit rate:
\[ \text{Unit rate (dollars per bag)} = \frac{\text{Total cost}}{\text{Number of bags}} = \frac{56.04}{9} \]
Now, perform the division:
\[ \frac{56.04}{9} \approx 6.22666667 \]
Rounding to the nearest hundredth:
\[ 6.23 \]
So, the unit rate of dollars per bag of chips is $6.23 per bag.
