Nate is making muffins. Each batch uses 2 cups of flour. He plans to use less than 40 cups of flour for muffins. How many more batches of muffins can Nate make?
Solve
Since each batch uses 2 cups of flour, Nate can make at most 40/2=<<40/2=20>>20 batches of muffins.
Therefore, Nate can make 20-1=<<20-1=19>>19 more batches of muffins. Answer: \boxed{19}.
