If a baker bakes 3 batches of cookies and makes 42 cookies, then the baker makes 42/3 = <<42/3=14>>14 cookies per batch.
Therefore, if the baker bakes 2 batches, the baker will make 14 x 2 = <<14*2=28>>28 cookies. Answer: \boxed{28}.
Therefore, if the baker bakes 2 batches, the baker will make 14 x 2 = <<14*2=28>>28 cookies. Answer: \boxed{28}.
So, 42 cookies divided by 3 batches equals 14 cookies per batch.
Therefore, if the baker bakes 2 batches, the total number of cookies made will be 14 cookies per batch multiplied by 2 batches, which equals 28 cookies.
We know that the baker made a total of 42 cookies with 3 batches. So, to find the number of cookies in each batch, we divide the total number of cookies by the number of batches:
42 cookies รท 3 batches = 14 cookies per batch
Now that we know there are 14 cookies in each batch, we can calculate the number of cookies made with 2 batches. We simply multiply the number of cookies per batch by the number of batches:
14 cookies per batch ร 2 batches = 28 cookies
Therefore, if the baker bakes 2 batches, they will make 28 cookies.
