Answer
125,000 tons of garbage per landfill
Explanation:
250 million total tons of garbage was sent to 2,000 landfills. Since it is assumed each landfill gets an equal amount of garbage, we can easily divide.
250,000,000 / 2,000 = 125,000 tons of garbage per landfill
henceforth, each landfill received 125,000 tons of garbage
