James buys jars for his honey. He has 5 hives that each produce 20 liters of honey. Each jar can hold .5 liters. How many jars will he need to buy if his friend is bringing his own jars for half the honey? Let's think first. Chain of thought:
He produces 5 * 20 = 100 liters of honey. That means he keeps 100 / 2 = 50 liters of honey. So he needs 50 / .5 = 100 jars.
Therefore, the answer is 100.
