Answer:
Each bag of Smart food, when you buy two and get two free, is worth $2.15.
Step-by-step explanation:
If you buy two bags of Smart food and get two bags for free, you will have a total of four bags. Since the offer is buy one, get one free, you are essentially paying for two bags and getting the other two bags for free.
Given that one bag costs $4.29, to find the value of each bag when you buy two and get two free, you need to divide the total cost by the total number of bags.
The total cost of two bags is $4.29 x 2 = $8.58. Since you also get two bags for free, the total number of bags is 4.
To find the value of each bag, you divide the total cost ($8.58) by the total number of bags (4):
$8.58 ÷ 4 = $2.15.
