Answer:
it is not possible to determine the exact amount of tablespoons of butter that Joey will need for the 10 pound sack of potatoes.
Explanation:
Joey needs to make sure he uses enough butter in his mashed potato recipe so that it will taste delicious. Based on the information provided, Joey needs to use the same ratio of butter to potatoes in order to maintain the recipe's desired taste.
However, without knowing the specific ratio used in Joey's recipe, it is not possible to determine exactly how many tablespoons of butter he will need for the 10 pound sack of potatoes. Additional information, such as the desired serving size, the number of people he is cooking for, or the amount of butter used in previous batches of mashed potatoes, would be needed to determine the exact amount of butter required.
In conclusion, without further information, it is not possible to determine the exact amount of tablespoons of butter that Joey will need for the 10 pound sack of potatoes.
