The function which best models the amount of rent she will have to pay in each future year is y = 450(1.15)^x

How to write a function

  • First year rent = $450
  • Percentage increase per year = 15%

let

y = total rent paid each subsequent year

x = number of years

The function:

y = 450(1.15)^x

If x = third year

y = 450(1.15)^x

= 450(1.15)^3

= 450(1.520875)

= $684.39375

Given options:

A) y = 0.15x + 450

B) y- 450x + 0.15

C) y = 450(1.15)^x

D) y = 450(0.15)^x
