Question

Michael is making cookies. Each batch uses 2 cups of flour. He plans to use less than 30 cups of flour so that he has enough left to make muffins. He has already used 4 cups. Let b represent the number of batches of cookies Michael can make. Which statement determines how many batches of cookies Michael can make?
A.Michael can make fewer than 13 batches of cookies.

B.Michael can make fewer than 14 batches of cookies.

C.Michael can make fewer than 15 batches of cookies.

D.Michael can make fewer than 26 batches of cookies.

Answer 1

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.

Answer 2

A. Michael can make fewer than 13 batches of cookies. is the correct answer here;

4+2b<30
-4        -4
2b<26
b<13
