Jason has already read 27 pages of a book. he plans to read 3 pages of the book every day. if f(n) represents the total number of pages that jason will complete reading in n days, which of the following functions represents the relationship between f(n) and n?

f(n) = 27n − 3
f(n) = 3n − 27
f(n) = 27n + 3
f(n) = 3n + 27

D.

Step-by-step explanation:

Total number of pages in a book=f(n)

Jason has already read pages=27

He plans to read pages of the book everyday=3

He takes times to complete reading the book=n days

He read pages in n days=3n

We have to find the function which represents the relationship between f(n) and n.

According to question information

This is required relation between f(n) and n.

answer: the price of one pound cabbage = $ 0.8

the point (10,8) represents that the cost of 10 pounds cabbage is $ 8

step-by-step explanation:

since, here is a proportional relation between the number of pounds of cabbage (x) and the price in dollars (y).

therefore, we can write,

⇒ y = k x

where k is the constant of proportionality.

now, point (5,4) is in the line.

thus, it will satisfies the above equation of line.

⇒ 4 = 5 k

⇒ k = 0.8

thus, the equation of the line is,

y = 0.8 x

a) for x = 1,

y = 0.8

therefore, the cost of one pound of cabbage is 0.8 dollars.

b) in the below graph (10,8) represents that the cost of 10 pounds of cabbage is 8 dollars.

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^
