Jessica is hiking in the mountains with her llama, her dog and her cat she comes to river where she must each animal across one at a time she has a problem she can't leave llama along with the dog, and she can't leave a cat alone with the dog, what is the fewest trips jessica can take to get the llama the dog and the cat the other side of the river

She takes the dog first, then the llama, then the cat. Easy. 3 trips hope I helped

First take the dog to the other side. Then take the llama across. When you get to where the dog is, drop the llama off and pickup the dog again. Take the dog to where the cat is. Drop off the dog, pick up the cat. Take the cat to the other side of the river, leave it with the llama. Go back, pick up the dog, and continue on! You need 4 round trips, or 8 one-way trips. Hope this helps you!

The answer of the above question is

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.
