Leslie works as a security guard at a concert hall. she earns $20 per hour for the first 40 hours she works each week. during a musical festival, she works overtime at a rate of $30 per hour. if her average hourly rate for that week was $22, how many hours of overtime did she work? a.) 10 b.) 20 c.) 22 d.) 50

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.
