The regular rolls are 15x - 2y = 4
The vegetarian rolls 20x - 3y = 1
So the values are:
x = 2 and y = 13
The result is, 2 chefs and 13 customers.

Im pretty sure there are 2 chefs and 13 customers, because the two chefs make 30 rolls with four left over making 26. of each costumer eats two that makes 13 customers.
