PLEASE HELP IF YOU CAN!!

Tina makes a table to use as a quick reference guide:

***Cookies baked (y) is a function of number of batches (x).***


Number of batches(X) ---->  Total number of cookies(Y)
X            Y
5   --->  180
6   --->  198
7   --->  216
8   --->  234
9   --->  252

How many cookies will Tina have if she has 7 more batches???

The Y factor is adding 18 so if you keep adding 18 till you get 16 in the x factor Tina will have 378 Batches.

To Figure Out How Create The Equation You Must Find What They Have In Common.
