Answer:
$4,116.
Explanation:
Beginning of 2015:
30% of 12000 = 30/100 x 12000 = 3600
The value in 2015: 12000-3600 = $8400.
The start of 2016:
30% of 8400 = 30/100 x 8400 = 2520
The value in 2016 = 8400-2520 = $5880.
Start of 2017
30% of 5880 = 30/100 x 5880 = 1764
Value in 2017 = 5880-1764 = $4116.
So, the value of his car at the start of 2017 is $4116.
Hope this helped and good luck! (:
