Answer:
4 rolls
Step-by-step explanation:
We can use logic to find how many rolls of toilet paper you would need.
If you use 10 sheets of toilet paper every time you use the toilet, and this happens 3 times a day, then each person per day uses sheets of toilet paper per day.
For a 4 family household with 4 people, that would be sheets every day for the whole family.
For a week (7 days) the whole family would use sheets per week.
If rolls of toilet paper are shipped by every 250 sheets, then we'd need rolls.
We can't have 0.36 of a roll, so we round up to 4 so we have enough.
Hope this helped!
