Answer:
C.
Step-by-step explanation:
The pythagorean theorem shows a^2+b^2=c^2.
a=8, b=15, c= the unknown distance
8^2+15^2=c^2
Take the 2 times you are given and add them to x and divide the entire left side of the equation by 3:
54.3+56.1+x/3=55
54.3+56.1+x=165
x=54.6
The 3rd lap took him 54.6 seconds to run
Divide both sides by 5 since there are 5 friends, you would get 5x-23.

Price decrease: $5,896
Price of the next model: $38,104
Explanations:
100 - 13.4 = 86.6/ 100 = 0.866
44000 x 0.866 = 38,104
44000 - 38104 = 5,896
A = 4 - 5c
a = 4 - 5(-1/2)
a = 4 - (-2.5)
a = 4 + 2.5
a = 6.5
