To find the unit rate of muffins per cup of almonds, we need to divide the total number of muffins by the total cups of almonds used.
Manny made 36 muffins and used 4 cups of almonds.
To calculate the unit rate:
\[ \text{Unit rate} = \frac{\text{Total muffins}}{\text{Total cups of almonds}} = \frac{36 \text{ muffins}}{4 \text{ cups}} = 9 \text{ muffins per cup} \]
So the unit rate of muffins per cup of almonds is 9 muffins.
