Answer:
C. 7
Step-by-step explanation:
Therefore, by Basic Proportionality theorem:

There are 7 days to a week, so 4 weeks = 4 * 7 = 28 days.
28 days x 2,500 kg per day = 70,000 total kgs.
Divide total kgs by kgs per ton:
70,000 total kgs / 907.2 kg per ton = 77.16 tons , round the answer to 77 tons.
