Step-by-step explanation:
Answer:
The worth of car at the start of 2014 = $12000
The value of the car decreased 30% every year.
At start of 2015:
30% of 12000 = \frac{30}{100} \times 12000
100
30
×12000 = 3600
So, the value of the car at start of 2015 = 12000-3600 = $8400.
At start of 2016:
30% of 8400 = \frac{30}{100} \times
8400
100
30
×8400 = 2520
So, the value of the car at start of 2016 = 8400-2520 = $5880.
At start of 2017:
30% of 5880 = \frac{30}{100} \times
5880
100
30
×5880 = 1764
the value of the car at start of 2017 = 5880-1764 = $4116.
So, the value of his car at the start of 2017 is $4116.
