in a fruit punch you mix 150 ml of lemonade with 250 ml of fruit
write the ratio of the volume of lemonade to the volume of fruits
give your ratio in its simplest form.

The ratio would be 150:250, but simplified, you would have to divide both sides by 50, the greatest common factor, or GFC. That would leave you with a simplified ratio of 3:5

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.
