Answer:
There should be enough food for 45 days
Step-by-step explanation:
The first step is to determine the number of people left at the hostel.
225 - 75 = 150
Multiply the people by the days to get food days.
225 * 30 = 6750 food days
Divide this by 150 (the new number of people).
6750/150 = 45
There should be enough food for 45 days.
