Answer:
Each postcard costs approximately $0.33.
Explanation:
To find the cost of each postcard, we can subtract the cost of the greeting card from the total cost of the postcards:
Total cost of postcards = Total cost - Cost of greeting card
Total cost of postcards = $5.11 - $3.79
Total cost of postcards = $1.32
Since Kaylin bought 4 postcards and they all cost the same amount, we can divide the total cost of the postcards by the number of postcards:
Cost of each postcard = Total cost of postcards / Number of postcards
Cost of each postcard = $1.32 / 4
Cost of each postcard ≈ $0.33
Therefore, each postcard costs approximately $0.33.
