This is a question from my younger sisters homework-

joshua's math test has 35 questions. if he answered 6/7th's of the correctly, how many questions did joshua answer correctly?

Well, if you separate 35 into seven parts, you get 5.  You'd then take 5 and multiply it by 6.  So

35÷7=5
6×5=30

Joshua answered 30 questions correctly.

30 is the answer since 7 goes into 35, 5 times and when you multiply 5 by 6 you get 30.

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.
