A brand new car costs $18,000, this price depreciates at 25% every year, how much would the car be after 12 years? 20 years?
Snezhnost [94]

Answer:

<em>C(12)=$570.18</em>

<em>C(20)=$57.08</em>

Step-by-step explanation:

<u>Exponential Decay Function</u>

The exponential function is often used to model natural growing or decaying processes, where the change is proportional to the actual quantity.

An exponential decaying function is expressed as:

C(t)=C_o\cdot(1-r)^t

Where:

C(t) is the actual value of the function at time t

Co is the initial value of C at t=0

r is the decaying rate, expressed in decimal

The depreciation of goods is often modeled as an exponential function. The new car costs $18,000 and its price depreciates at r=25%= 0.25 every year.

The depreciation model is:

C(t)=18,000\cdot(1-0.25)^t

Operating:

C(t)=18,000\cdot 0.75^t

At t=12 years, the price will be:

C(12)=18,000\cdot 0.75^{12}

C(12)=$570.18

At t=20 years, the price will be:

C(20)=18,000\cdot 0.75^{20}

C(20)=$57.08

Bogdan [553]

Answer:

Rate of interest r = 2.83 % (Approx.)

Step-by-step explanation:

Given:

Amount invested p = $2,600

Amount get A = $4,300

Number of year n = 18

Find:

Rate of interest r

Computation:

A = p(1+r)ⁿ

4,300 = 2,600(1+r)¹⁸

(1+r)¹⁸ = 1.653846

Rate of interest r = 2.83 % (Approx.)
