C is 27/40. If you add it to 1/8 and simplify, you get 4/5.
F(x)=2(3)-5
f(x)=6-5
f(x)=1
To get the answer we can use proportion.
30----------100%
12-----------x
Cross multiply now
30x=12*100%
30x=1200% /:30 (divide both sides by 30)
x=40% - it's the percentage of cars which finished the race.
100%-40%=60% - it's the answer
