A swim race has a total distance of 25 mi Race officials want to mark the course every 500yd with buoy, including one at the finish line. How many buoys are needed?

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.

It will cost $540i think
