If you know that 8x300=2400 how can you find 8x320

If you knew that 8*300=2400

Then you could likely figure that 8*20=160

And then just add the two together to get 2560

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.
