£7200
In first year depreciates by 20%, that is it is worth 80% of it's original value
80% =
= 0.8
value after 1 year = 0.8 × £10000 = £8000
In the second year it depreciates by 10% of it's value, that is it is worth 90% of it's value at the end of the first year.
90% =
= 0.9
value after 2 years = 0.9 × £8000 = £7200

3x(2x+3y)
1. find a common multiple of either sides of the + sign...
3x
2. put it outside the brackets...
3x( )
3. find what you have to multiply the rest equation by to get the number...
2x x 3x = 6x squared
3y x 3x = 9xy
4. put it in the brackets...
3x(2x+3y)

Answer:
A. V = 116050 - 5300t
B. $73,650.
Step-by-step explanation:
10050 = 116050 - 20k where k is the depreciation every year.
20k = 116050 - 10050 = 106000.
k = 106000 / 20
k = 5300
So the answer to A is:
V = 116050 - 5300t where t = number of years old the bulldozer is.
B. Value after 8 years
= 116050 - 5300*8
= 73,650 dollars.
