Question: A smartphone currently is worth $175 and depreciates at 25% per year. What will the value be in 3 years?
What equation do I use to solve this?

Answer 1

loses 25% of its value means it retains 75% of its value
use \(175\times .75^t\)

Answer 2

eqquation close to p=(1+r/100)^n
n=number of years
compound interest

Answer 3

or if you prefer \(175\times (\frac{3}{4})^t\) either way
you want \(175\times (.75)^3\) and a calculator is needed for this one

Answer 4

well done satellite
