a) Alejandro: 2 pages per minute, Carly: 1 page per minute
b) Alejandro: 1 page per minute, Carly: 2 pages per minute
c) Alejandro: 28 pages per minute, Carly: 12 pages per minute
d) Alejandro: 12 pages per minute, Carly: 28 pages per minute

Answer 1

Alejandro's rate of change is 1 page per minute, and Carly's rate of change is 2 pages per minute. The correct option is b) Alejandro: 1 page per minute, Carly: 2 pages per minute.

Step-by-step explanation:

The rate of change for a student's reading speed is the amount of pages they can read per minute. In the case of Alejandro and Carly, their rates of change are given by the number of pages read per minute. Alejandro can read 1 page per minute, and Carly can read 2 pages per minute.

Therefore, the correct answer to the question of what the rate of change is for each student is: Alejandro: 1 page per minute, Carly: 2 pages per minute. Hence, the answer is option b) Alejandro: 1 page per minute, Carly: 2 pages per minute.
