Answer:
120 bottles of water are needed. 3 cases are needed.
Step-by-step explanation:
If there are 60 people and they each have 2 bottles of water, we know that there are 120 bottles in total, 60x2 = 120.
There are 40 bottles in one case. Knowing this, we divide 120 by 40 to get that 3 cases are needed.
