Answer:
350% mark up
Step-by-step explanation:
To find the percent markup
Take the new price and subtract the original price
72-16 =56
Then divide by the original amount
56/16
3.5
Change to percent form
350%
The value of the car after three years is £6936
<h3>How to determine the value of the car?</h3>
The initial value of the car is given as:
Value = £12000
When the value depreciates by 20% after the first year, the new value of the car is:
New = £12000 * (1 - 20%)
Evaluate
New = £9600
When the value depreciates by 15% after the second year, the new value of the car is:
New = £9600* (1 - 15%)
Evaluate
New = £8160
When the value depreciates by 15% after the third year, the new value of the car is:
New = £8160 * (1 - 15%)
Evaluate
New = £6936
Hence, the value of the car after three years is £6936

Given:
are three interior angles of any triangle.
To prove:
![\cos (\alpha+\beta+\gamma)=-1](https://tex.z-dn.net/?f=%5Ccos%20%28%5Calpha%2B%5Cbeta%2B%5Cgamma%29%3D-1)
Solution:
According to the angle sum property of a triangle, the sum of all three interior angle of a triangle is always 180 degrees.
It is given that,
are three interior angles of any triangle.
Using the angle sum property of triangles, we get
...(i)
We need to prove,
![\cos (\alpha+\beta+\gamma)=-1](https://tex.z-dn.net/?f=%5Ccos%20%28%5Calpha%2B%5Cbeta%2B%5Cgamma%29%3D-1)
Taking LHS, we get
![LHS=\cos (\alpha+\beta+\gamma)](https://tex.z-dn.net/?f=LHS%3D%5Ccos%20%28%5Calpha%2B%5Cbeta%2B%5Cgamma%29)
[Using (i)]
![LHS=-1](https://tex.z-dn.net/?f=LHS%3D-1)
![LHS=RHS](https://tex.z-dn.net/?f=LHS%3DRHS)
Hence proved.
