Larry Mcguire · Answer 2

D. Emma read 15 pages of her novel each hour.

Step-by-step explanation:

Earning 2% interest means the amount of interest, in terms of dollar amounts, changes every year. This is not a constant rate of change.

Doubling the production means the amount of extra production changes every year. This is not a constant rate of change.

A value of 0.8 times the value the previous year means the amount of decrease changes every year. This is not a constant rate of change.

Reading 15 pages of a novel every hour means that every hour, the number of additional pages read is the same. This is a constant rate of change.
