Answer:
50
Step-by-step explanation:
If she has 6 boxes, and each box has 25, then the total number of cups of blueberries is 25*6 which is 150. Then, if she uses 3 cups of blueberries for each pies, then we can divide 150/3 to get 50, which is the total blueberry pies that the bakery can make using all the blueberries she ordered.
