There are 24 hours in a day scientists tell us that we should sleep for 3/8 of a day how much time should we spend sleeping

When you have to find the part of a number, remember that you have to multiply the two numbers (fraction and whole number)

In a day there are 24 hours.
3/8 of a day
Process:
24 X 3/8 = 9
We sleep 9 hours of the day.

Bascially you go 3/8 = .375 Then multiply .375 x 24 = 9

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.
