To find the unit rates, we need to calculate how many bags of chips there are per dollar and how many dollars there are per bag of chips.

  1. Bags of chips per dollar:

    • We have 6 bags of chips costing $45.51.
    • First, we find out how many dollars correspond to one bag of chips by dividing the total cost by the number of bags: \[ \text{Cost per bag} = \frac{45.51}{6} \approx 7.585 \]
    • Now, to find the bags of chips per dollar, we take the reciprocal of the cost per bag: \[ \text{Bags per dollar} = \frac{1}{7.585} \approx 0.131 \]

  2. Dollars per bag of chips:

    • We already calculated the cost per bag: \[ \text{Dollars per bag} = 7.585 \]

Now, rounding to the nearest hundredth:

  • The unit rate for bags of chips per dollar is approximately 0.13 bags per $.
  • The unit rate of dollars per bag of chips is approximately $7.59 per bag.

So, the final answers are:

  • The unit rate for bags of chips per dollar is approximately 0.13 bags per $.
  • The unit rate of dollars per bag of chips is $7.59 per bag.
