Ответ:
(JSYK: this is all considering that only whole batches are included and fractional batches aren't)
3 batches (72 cookies), her limiting reactant should be sugar since she only has enough to make three batches exactly, and she will also have 3/4 a cup of flour left over, 2 cups butter, and 5 eggs, in addition to the excess of baking soda and baking powder.
Hope this helps, if not, comment below please!!!
