A £20 000 car depreciates by 12% per year. How much is it worth after five years?

£8000

Step-by-step explanation:

Since the car depreciates at 12% every year

So we will have to determine the amount that is depreciated for the first year

So let's solve

12/100×20000

12×200

2400

2400 is the amount depreciated every year so to determine for 5 years it will be

2400×5

12000

£12000 is the amount depreciated for 5years

So to determine the amount he bought the car after the five years

It will be 20000-12000

=8000

Therefore he bought the car £8000 after the fifth year

Php 3,230

Step-by-step explanation:

1. calculate x= the number of days worked in a week (5days)

which is,

x= 5 (no of days) x 550 ( total amount of Php received in a day)

x= Php 2,750

2. calculate y= the number of extra hours ( 6 hours )

which is,

y= 6 ( total number of extra hours ) x 80 ( because extra hours is paid at the amount of Php 80 )

y= Php 480

3. Add x and y to get the final answer

which is,

Php 2,750 + Php 480 = Php 3,230
