Question

The function f, where f(n)=1200n+3500 represents the number of people in a town who owned a smartphone n years after 2007. How many people owned a smartphone in this town in the year 2010? ​

Answer 1

Answer:

$7,100\ people$

Step-by-step explanation:

we have

$f(n)=1200n+3500$

where

f(n)---> represents the number of people in a town who owned a smartphone

n ---> the time in years after 2007

In the year 2010

The value of n is

n=2010-2007=3

so

For n=3 Evaluate f(3)

$f(3)=1200(3)+3500$

$f(3)=7,100\ people$
