12.75/y = z 

make sure you note that Carlos is included in the"number of friends". Otherwise, it will be 12.75/(y +1) = z.

31356 · Answer

Or:
z = 12.75 / y 

Because, the total cost divided by the number of people present will tell you how much each person should pay. Here, the total cost is 12.75 and we will divide by number of people (y) to get the amount each person pays (z)
