Your answer is A. Michael can make fewer than 13 batches of cookies
If he has 30 cups of flour and has already used 4, subtract.
=26
so he has 26 cups of flour and it takes two cups to each batch, so divide.
26/2=13
if the two batches he has already made are included in the problem, then your answer would actually be C. but I don't think that's the case.
