Alittle league team played a
doubleheader (two back-to-back
baseball games). the first game lasted
155 minutes. the second game lasted
175 minutes. there was a 30-minute
break between games. what was the
total time of the doubleheader?

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.
