Jamal made a line plot to show many cups of laundry soap his family used each week for 10 weeks.
Laundry Soap (cups)
Jamal finds the total cups of laundry soap used during the 4 weeks when his family used the greatest amount of laundry soap.
If this total amount of laundry soap is used equally in each of those 4 weeks, how many cups of laundry soap would be used each week?
