Solution

The constant of proportionality, also known as the rate of change, can be found by dividing the total number of pages read by the total number of days.

From the table, we can see that on day 2, Daria has read 56 pages. So, we divide 56 pages by 2 days to get 28 pages per day.

Similarly, on day 4, she has read 112 pages. We divide 112 pages by 4 days to get 28 pages per day.

Finally, on day 6, she has read 168 pages. We divide 168 pages by 6 days to get 28 pages per day.

So, the constant of proportionality in pages read per day is 28.
