Baby Amelia's parents measure her height every month.

H (t) models Amelia's height (in centimeters) when she was t months old.

What does the statement H (30) = H (25) + 5 mean?

The statement H (30) = H (25) + 5 means that, "when Amelia was 30 months old, she was 5 centimeters taller than when she was 25 months old"

Solution:

Given that,

Baby Amelia's parents measure her height every month

It is given that H (t) models Amelia's height (in centimeters) when she was "t" months old

Given statement is H (30) = H (25) + 5

So, we can say that H (30) = Amelia's height when she was 30 months old

H (25) = Amelia's height when she was 25 months old

So H (30) = H (25) + 5 means that,

Height of Amelia when she was 30 months old is 5 centimeter more than Amelia height when she was 25 years old

Or we can say that,

When Amelia was 30 months old, she was 5 centimeters taller than when she was 25 months old
