A person borrows 15,000 for two years. Interest for the first year is charged at 12% per annum. The person repays 6,000 at the end of the first year. If the amount owed at the end of the second year is 12,042 find the rate of interest for second year.

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.
