Aneli [31]

Answer:

The ratio of x:y is 1/2

Step-by-step explanation:

Let

x----> the number of Kg of brand A

y ---> the number of Kg of brand B

we know that

400x+280y=320(x+y)

400x+280y=320x+320y

lions [1.4K]

Answer:

Actual value after 5 years is £1344 more than John's value.

Step-by-step explanation:

Johns estimate:-

V = k/t (inverse proportionality)   where V = value of the car and t = it's age.

When t = 2, V = £12,000:-

12,000 = k/2 giving k = 24,000

Therefore the value at 5 years of age, according to John's proposition is

V = 24,000 / 5  =  £4,800

The actual value using the given depreciation is

12000(1 - 0.2)^3 = £6144

Difference is  £1344
