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

The fourth choice is correct.
27 would be the Y intercept, and 3n would be the slope.
f(n) = 3n + 27

Answer:

D.
f(n)=3n+27

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


f(n)=3n+27

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

Answer:D.
f(n)=3n+27
