To get the answer we can use proportion
2/5 ------------------ 203
3/5 ------------------ x
crossmultiply now
3/5*203=2/5*x
$\frac{609}{5} = \frac{2}{5} x \\ 609=2x \\ x=304.5$ - its the answer

Dan buys a car for £2100.

SVETLANKA909090 [29]

Answer:

£1837.5

Step-by-step explanation:

Given data

Cost of car P= £2100.

Rate r= 2.2%

Time t= 6 years

Now we want to find the worth after 6 years, let us apply the compound interest expression but this time for depreciation

A= P(1-r)^t

Substitute

A= 2100(1-0.022)^6

A= 2100*(0.978)^6

A= 2100*0.875

A= £1837.5

Hence the amount of the car after 6 years is £1837.5
