Based on the line plot you described, the amount of milk in cereal shows the following amounts:
- 1/2 cup (4 occurrences)
- 3/4 cup (3 occurrences)
- 1 cup (1 occurrence)
From this information, we can determine that:
- The least amount of milk poured is 1/2 cup.
- The most amount of milk poured is 1 cup.
To find out how much more milk Maureen's father poured on the day he poured the most (1 cup) compared to the day he poured the least (1/2 cup), we subtract the least from the most.
1 cup - 1/2 cup = 1 - 1/2 = 1/2 cup.
So, the answer is:
1/2 Cups.
