Beth and Ben work together in a store. The expression 12h + 50 represents the amount of money Beth earns, and the expression 14h - 20 represents the amount of
money that Ben earns. The variable h represents hours worked, and the integers
represent dollar amounts. Find an expression that gives the total amount of money
earned by Beth and Ben when they work together for h hours.

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.
