Step-by-step explanation:

See attachment for tables

Given

p = 3.25b

Required

Which of the tables is more expensive than the given function

To answer this question, we simply determine the equation of each table and then compare the equation with p = 3.25b

Table A:

Consider two corresponding points in the table, we have:

(b_1,p_1) = (1,2.75)

(b_2,p_2) = (4,11)

Determine the slope

$m = \frac{p_2 - p_1}{b_2 - b_1}$

$m = \frac{11 - 2.75}{4 - 1}$

$m = \frac{8.25}{3}$

m = 2.75

The equation is determined as follows:

p - p_1 = m(b-b_1)

p - 2.75 = 2.75(b-1)

p - 2.75 = 2.75b-2.75

p = 2.75b

Comparing this equation to p = 3.25b , we have that:

2.75 < 3.25

Hence:

This equation is less expensive than p = 3.25b

Table B:

Consider two corresponding points in the table, we have:

(b_1,p_1) = (1.5,3.75)

(b_2,p_2) = (6,15)

Determine the slope

$m = \frac{p_2 - p_1}{b_2 - b_1}$

$m = \frac{15 - 3.75}{6 - 1.5}$

$m = \frac{11.25}{4.5}$

m = 2.5

The equation is determined as follows:

p - p_1 = m(b-b_1)

p - 3.75 = 2.5(b-1.5)

p - 3.75 = 2.5b- 3.75

p = 2.5b

Comparing this equation to p = 3.25b , we have that:

2.5 < 3.25

Hence:

This equation is also less expensive than p = 3.25b

Table C:

Consider two corresponding points in the table, we have:

(b_1,p_1) = (2,7)

(b_2,p_2) = (4,14)

Determine the slope

$m = \frac{p_2 - p_1}{b_2 - b_1}$

$m = \frac{14 - 7}{4 - 2}$

$m = \frac{7}{2}$

m = 3.5

The equation is determined as follows:

p - p_1 = m(b-b_1)

p - 7 = 3.5(b - 2)

p - 7 = 3.5b - 7

p = 3.5b

Comparing this equation to p = 3.25b , we have that:

3.5 3.25

Hence:

This equation is more expensive than p = 3.25b

Table D:

Consider two corresponding points in the table, we have:

(b_1,p_1) = (2.5,10)

(b_2,p_2) = (5,20)

Determine the slope

$m = \frac{p_2 - p_1}{b_2 - b_1}$

$m = \frac{20 - 10}{5 - 2.5}$

$m = \frac{10}{2.5}$

m = 4

The equation is determined as follows:

p - p_1 = m(b-b_1)

p - 10 = 4(b - 2.5)

p - 10 = 4b - 10

p = 4b

Comparing this equation to p = 3.25b , we have that:

4 3.25

Hence:

This equation is more expensive than p = 3.25b

Table E:

Consider two corresponding points in the table, we have:

(b_1,p_1) = (6, 22.5)

(b_2,p_2) = (12,45)

Determine the slope

$m = \frac{p_2 - p_1}{b_2 - b_1}$

$m = \frac{45 - 22.5}{12 - 6}$

$m = \frac{22.5}{6}$

m = 3.75

The equation is determined as follows:

p - p_1 = m(b-b_1)

p - 22.5 = 3.75(b - 6)

p - 22.5 = 3.75b - 22.5

p = 3.75b

Comparing this equation to p = 3.25b , we have that:

3.753.25

Hence:

This equation is more expensive than p = 3.25b

Table F:

Consider two corresponding points in the table, we have:

(b_1,p_1) = (7, 21)

(b_2,p_2) = (14,42)

Determine the slope

$m = \frac{p_2 - p_1}{b_2 - b_1}$

$m = \frac{42 - 21}{14 - 7}$

$m = \frac{21}{7}$

m = 3

The equation is determined as follows:

p - p_1 = m(b-b_1)

p -21 =3(b -7)

p -21 =3b -21

p = 3b

Comparing this equation to p = 3.25b , we have that:

3 < 3.25

Hence:

This equation is less expensive than p = 3.25b

answered: Guest

the answer would be d

straight away you can eliminate a and c because not all books contain a scientific skill because some may be fiction. c is also wrong because it saids that the only way children can learn is through books which is incorrect.

b is also wrong because reading can be a scientific skill but not always, therefore it is wrong which leaves you with d, the correct answer since it said that it can children learn.

hope this ! : 3
