Answer 2

Answer:

$14,080

Step-by-step explanation:

At end of first year:

$22,000 will decrease by 20%. It means to subtract 20% of 22,000 from 22,000.

20% of 22,000 is  $(0.2)(22,000)=4,400$

Now, $22,000-4,400=17,600$

At end of second year:

$17,600 will decrease by 20%. It means to subtract 20% of 17,600 from 17,600.

20% of 17,600 is  $(0.2)(17,600)=3520$

Now,  $17,600-3,520=14,080$

Hence, $14,080 is the value of the car at the end of 2 years. First answer choice is right.
