To find the unit rate of rolled oats per cup of almonds, you divide the amount of rolled oats by the amount of almonds.
Maria uses 6 cups of rolled oats and 2 cups of almonds.
The unit rate of rolled oats per cup of almonds is calculated as follows:
\[ \text{Unit rate} = \frac{\text{Rolled oats}}{\text{Almonds}} = \frac{6 \text{ cups of rolled oats}}{2 \text{ cups of almonds}} = 3 \]
So, the unit rate of rolled oats per cup of almonds is 3 cups.
