Concept

Depreciation occurs with time. A product or item loses it value of a time period by a certain percentage.

Given

Mikes car was worth £12,000 at start of 2014.

Find

The value of the car at the start of 2017.

Solution

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 = $\frac{30}{100} \times 12000$

= 3600

So, the value of the car at start of 2015 = 12000-3600 = $8400.

At start of 2016:

30% of 8400 = $\frac{30}{100} \times 8400$

= 2520

So, value of the car in the start of 2016 = 8400-2520 = $5880.

At start of 2017:

30% of 5880 =$\frac{30}{100} \times 5880$

= 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.
