## Question:

The salvage value S (in dollars) of a company limousine after t years is estimated to be given by the formula below. Use the formula to answer the question.

S(t) =500,000(0.6){eq}^t {/eq}

What is the rate of depreciation(in dollars per year) after 1 year?

## Average Rate of Change:

From the formula {eq}\frac{f(b)-f(a)}{b-a} {/eq}, the average rate of change for a function approximates the change between two points to approximate the overall constant rate of change for a function as the input increases.
