How many cookies will Tony have if he bakes 10 batches more than the maximum number of batches in the table

since for every one batch there is increasement of 18 cookies so 10 more batches are added so............
12 + 10 = 22 total batches and the no. or cookies
306 + 10×18
306 + 180
486
so he will have 486 cookies idk what he will do with that much of cookies but he probably end up with diabetes
