To find out the cost of each cheeseburger, we need to subtract the tax from the total and then divide that amount by the number of cheeseburgers.
Given:
Total cost = $17.65
Tax = $1.25
Number of cheeseburgers = 4
First, we subtract the tax from the total to find the cost of the cheeseburgers alone:
Total cost - Tax = $17.65 - $1.25 = $16.40
Next, we divide the cost of the cheeseburgers by the number of cheeseburgers to find the cost per cheeseburger:
Cost per cheeseburger = $16.40 / 4 = $4.10
Therefore, each cheeseburger costs $4.10.
I hope it helps.
