To find the total cost, we calculate the cost for each item and sum them up.

1. Cost of 33 bags of chips
   $33 \times 2.79 = 91.97$

2. Cost of 33 hot dogs
   $33 \times 1.59 = 52.47$

3. Cost of 11 bottles of orange juice
   $11 \times 1.69 = 18.59$

4. Total cost
   $91.97 + 52.47 + 18.59 = 163.03$

Final Answer:

Autumn's total cost is $163.03.
