the current value of a new car is 18,000. the car will depreciate 15% per year over the next 5 year. which exponential equation
Arte-miy333 [17]

The exponential equation that models this situation is:

V(t) = 18000(0.85)^t, 0 \leq t \leq 5.

<h3>What is an exponential function?</h3>

A decaying exponential function is modeled by:

A(t) = A(0)(1 - r)^t

In which:

  • A(0) is the initial value.
  • r is the decay rate, as a decimal.

For this problem, the parameters are:

A(0) = 18000, r = 0.15.

Hence the equation for the value of the car over the next 5 years is:

A(t) = A(0)(1 - r)^t

A(t) = 18000(1 - 0.15)^t

V(t) = 18000(0.85)^t, 0 \leq t \leq 5.
