To find the unit rate of muffins per cup of almonds, you can divide the number of muffins by the number of cups of almonds.
Manny makes 36 muffins and uses 4 cups of almonds.
Unit Rate = Number of Muffins / Number of Cups of Almonds Unit Rate = 36 muffins / 4 cups = 9 muffins per cup.
So the correct answer is:
9 muffins.
