The area of the trapezoid is 77 inches^2
So the original price paid for the car is 19,750, then it went up to 23,950, so pretty much 4,200 more, namely the markup.
if we take 19750 as the 100%, what is 4200 off of it as a percentage?
Congrats on your first question!

Answer:
Ron runs the fastest.
Step-by-step explanation:
To see who's the fastest you should convert everyone's speed into one unit (feet per second for this example).
Liz
13 feet per second (doesn't have to be converted).
Ron
He runs 495 feet in 34 seconds, so he runs 495 feet ÷ 34 ≅ 14.55882 feet per second.
Katie
1 mile = 5280 feet. She runs 5280 feet in 506 seconds, so she runs 5280 ÷ 506 ≅ 10.43478 feet per second.
Will
1 minute = 60 seconds. He runs 666 feet in 60 seconds, so he runs 666 ÷ 60 = 11.1 feet per second.
Results
Liz - 13 feet per second
Ron - 14.55882 feet per second
Katie - 10.43478 feet per second
Will - 11.1 feet per second
As the results show, Ron runs the fastest, Liz the second fastest, Will the third fastest and Katie the fourth fastest.
