To find the unit rate, we need to determine how many tablespoons of chocolate powder are used for 1 cup of milk.
From the given information, Mixture X uses:
- 3 cups of milk for 4 tablespoons of chocolate powder.
To find the amount of chocolate powder per cup of milk, we can set up the following calculation:
\[ \text{Chocolate Powder per Cup of Milk} = \frac{\text{Total Chocolate Powder}}{\text{Total Cups of Milk}} = \frac{4 \text{ tablespoons}}{3 \text{ cups}} \]
Now, we need to simplify this to find the amount for just 1 cup of milk:
\[ \text{Chocolate Powder per 1 Cup of Milk} = \frac{4 \text{ tablespoons}}{3} \approx 1.33 \text{ tablespoons} \]
Thus, for 1 cup of milk, there are approximately 1.33 tablespoons of chocolate powder.
