To determine how much you save per dozen bags by buying in bulk, you can calculate the total cost of buying individual bags and then compare it to the bulk price.
-
Cost of buying individual bags:
- Price per bag: $0.99
- Number of bags in a dozen: 12
- Total cost for a dozen bags at the local store: \[ 0.99 , \text{(price per bag)} \times 12 , \text{(number of bags)} = 11.88 \]
-
Cost of buying in bulk:
- Total cost for the bulk bag of 12 smaller bags: $10.50
-
Calculate the savings:
- Savings = Cost of individual bags - Cost of bulk bag \[ \text{Savings} = 11.88 - 10.50 = 1.38 \]
Thus, you save $1.38 per dozen bags by buying in bulk.
