Question

a new motor home costs $89000. It is expected to depreciate 9% each year.Find the value of the motor home in 4 years.

Answer 1

The function which represents the situation is:

$\boxed{y=89000*(0.91)^t}$

where t is the time in years and y is the depreciated value of the motor.

In 4 yars value will depreciated to:

$y=89000(0.91)^4\\ \\ y=89000(0.6857)\\ \\ \boxed{y=US\ \ 61031.71}$
