Rex is searching for bread and discovers trhat he has 40 buns for every 10 cubes of cheese. if he has 80 buns, how many cubes of c heese does he have?

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.

Think of it as five or above give it a shove. change the 5 or above to the right to a zero and add one to the number on the left.

B. 16in. x 20in , is your best bet
