Answer 2

Here we are given the equation:

$y=10000*(0.97)^{x}$

Here x represents the year.

Now plugging the value of x for different year :

A. x=1,

$y=10000*(0.97)^{1}$

y=9700

option A. 1 year is correct.

B. x=2,

$y=10000*(0.97)^{2}$

y=9404

But in the option we are given y=9308

So option B is incorrect.

C. x=3,

$y=10000*(0.97)^{3}$

y=9126.73

y= 9127 ( approx.)

So option C is correct.

D. x=4

$y=10000*(0.97)^{4}$

y=8852.9

y=8853 (approx)

So option D is also correct

Answer : option C. 3
