The zoo has two alligators named Lucky and Linus. Lucky is 4 feet long and Linus is 8 feet long. Melinda predicts that two years from now, Lucky will be about 9 feet long and Linus will be about 13 feet long.

Over the next two years, will both reptiles grow the same amount? How do you know?

Olivia said that each alligator grew the same number of feet. Pablo disagrees. What is a viable argument he could make to convince Olivia that he is correct? Create a visual model to explain your thinking.

Please help me with these! I think I might know the answer, but I wanna make sure I am correct. Please include reasoning and answer exactly and all of what the question is asking :)

Lucky = 4 feet
Linus = 8 feet

In two years,
Lucky = 9 feet
Linus = 13 feet

Therefore:
Lucky grew: 9 feet - 4 feet = 5 feet
Linus grew: 13 feet - 8 feet = 5 feet

So over the next two years, they both will grow the same amount because they both grew exactly 5 feet.

One way to draw a visual model is to use a number line which I can't type in this answer box.
