HELP PLEASE I NEED HELP! In the Central Grand Prix, out of 30 cars that started the race, 12 of them finished. What percent of the cars finished the race ? What percent of the cars did not finish the race ?

In all honesty, there really is no “work” per say to show. mainly it’s just using the process of elimination. the question is asking which domain(s) would be the most appropriate for the function c(n). n is the number of observed vehicles so right away, 1, 2, and 3 can be eliminated.why? 1, 2 start in the negatives and therefore it is impossible to observe negative cars. so, #4 would be the best answer to the given problem.
