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.

D.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
