Answer 1

The unit rate per ounce of vanilla for Tallie's Grandma's cookie recipe is 12 cups of oatmeal per ounce of vanilla.

Step-by-step explanation:

To calculate the unit rate per ounce of vanilla for Tallie's Grandma's cookie recipe, we need to determine how much oatmeal is used for each ounce of vanilla. The recipe calls for 3 cups of oatmeal for every ¼ ounce of vanilla. To find the amount of oatmeal per ounce of vanilla, multiply the amount of oatmeal by 4, since there are 4 quarters in a whole (4 ¼ ounces = 1 ounce).

Therefore, the calculation is as follows:

• 3 cups of oatmeal × 4 = 12 cups of oatmeal per ounce of vanilla.

So the correct unit rate per ounce of vanilla is 12 cups per ounce of vanilla.
