In hopes of encouraging healthier snacks at school, Kirk brought in a tray of carrot sticks and apple slices to share. He brought 12 carrot sticks and 18 apple slices. What percentage of the snacks were carrot sticks? Write your answer using a percent sign (%).

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.
