number of days, d | calculation | number of pages, p
1 | 1·20 | 20

Explanation:

Step1: Identify daily page rate

From the given row, Noah reads 20 pages per day, so the relationship is $p = 20d$.

Step2: Calculate for day 2

Multiply days by 20.
$2 \times 20 = 40$

Step3: Calculate for day 3

Multiply days by 20.
$3 \times 20 = 60$

Step4: Calculate for day 4

Multiply days by 20.
$4 \times 20 = 80$

Step5: Calculate for day 5

Multiply days by 20.
$5 \times 20 = 100$

Step6: Calculate for day 6

Multiply days by 20.
$6 \times 20 = 120$

Step7: Calculate for day 7

Multiply days by 20.
$7 \times 20 = 140$

Answer:

Number of Days, $d$	Calculation	Number of Pages, $p$
2	$2 \times 20$	40
3	$3 \times 20$	60
4	$4 \times 20$	80
5	$5 \times 20$	100
6	$6 \times 20$	120
