Monthly rent at Lake View Apartments has increased annually and is modeled by the exponential equation y = 2,400(1.04)x. What is the percent increase per year?

Respuesta :

Answer:

The percent increase per year is 4%

Step-by-step explanation:

we have

[tex]y=2,400(1.04^x)[/tex]

This is a exponential function of the form

[tex]y=a(b^x)[/tex]

where

y represent the monthly rent at Lake View Apartments

x represent the number of years

a is the initial value (y-intercept)

b is the base

r is the rate or percent increase

[tex]b=(1+r)[/tex]

The percent increase per year is the base of the exponential function decreased by 1.

so

[tex]r=b-1[/tex]

In this problem we have

[tex]a=\$2,400[/tex] ---> initial value

[tex]b=1.04\\r=1.04-1=0.04=4\%[/tex]

Therefore

The percent increase per year is 4%

Answer:

B. 4% every year
