Answer:

Let the cost of each bag of potatoes be x.

Then, the total cost of 4 bags of potatoes would be 4x.

According to the problem, Serenity pays a total of $31.69.

This can be written as:

4x + 4.09 = 31.69

Subtracting 4.09 from both sides, we get:

4x = 27.60

Dividing both sides by 4, we get:

x = 6.90

Therefore, each bag of potatoes costs $6.90.
