Gabrielle’s age is two times Michaels age. The sum of their ages is 39. What is Mikhails age?

39divided by 2
=19

19+19=38 BUT it still rounds up to 39.

Ican't do any of the other stuff, but i can get you started. the answer, i believe, is $2.50.

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.
