Question

A buisness purchases a computer I

system for $3,000. The value
of the system decreases at a rate
of 15% per year. Which expotential
function models this situation.

Answer 1

`V(y) = 3000(0.85)^(y)`

Explanation:

A business purchases a computer I system for $3,000. The value of the system decreases at a rate of 15% per year.

Therefore, the yearly valuation decay rate is
`(15)/(100) = 0.15`.

Now, using the exponential function modeling we can write,

`V(y) = 3000(1 - 0.15)^(y) = 3000(0.85)^(y)`

Here, V(y) is the valuation of the computer after y years of purchase.

$3000 is the initial value. (Answer)
