Question

At the start of 2014 Mikes car was worth 12000

Answer 1

Answer:

The value of the car decreased 30% every year. So, the value of the car at start of 2015 = 12000-3600 = $8400

Answer 2

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

So, 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.
