Two students were asked to find the value of a $1000 item after 3 years. The item was depreciating (losing value) at a rate of 4

Answer:

<em>Student 2 is incorrect because he didn't use the formula properly</em>

Step-by-step explanation:

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 initial value of the item is Co=$1000, the rate of decay is r=40%=0.4, and the time is t=3 years.

Substituting into the formula:

$C(3)=\$1000\cdot(1-0.4)^3$

$C(3)=\$1000\cdot0.6^3$

C(3)=$216

Student 2 is incorrect because he didn't use the formula properly
