We substitute the given information to obtain:
We simplify to obtain:
To find the markup, substract the price at which the car was bought from the price at which the car was sold:
To find the markup as a percentage from the original price, set 20,480 to be equal to 100%. If <em>x%</em> represents 6328, then:
To the nearest tenth, 30.898... = 30.9.
Therefore, the markup is equal to 30.9%.

Step-by-step explanation:
Answer:
x=60
Step-by-step explanation:
The sum of interior angles of a regular Pentagon is 540°
x+2x+2.5x+x+10+2x+20=540
8.5x=540-30
8.5x=510
x=510/8.5=60
If Z= 3 (example)
6xZ= 18
I'm assuming that you would need to find Z first, so you just multiply Z by 6 once you've found it.
