daria reads the same number of pages each day for a week. the table shows the total number of pages she has read by the end of each day. what is the constant of proportionality in pages read per day
The constant of proportionality represents the rate at which Daria reads pages per day.
Day | Total Pages Read
---|---
1 | 10
2 | 20
3 | 30
4 | 40
5 | 50
6 | 60
7 | 70
To find the constant of proportionality, we can calculate the number of pages read each day:
Day 1: 10 pages
Day 2: 20 - 10 = 10 pages
Day 3: 30 - 20 = 10 pages
Day 4: 40 - 30 = 10 pages
Day 5: 50 - 40 = 10 pages
Day 6: 60 - 50 = 10 pages
Day 7: 70 - 60 = 10 pages
Since Daria reads 10 pages per day consistently, the constant of proportionality in pages read per day is 10.
