the amount of money rachel earns varies directly with the number of hours she works. if sue earns $600 when she works 40 hours , how much will she earn for working 85 hours ?

1,275
Explanation : If she earns 600 dollars working for 40 hours, you can find the amount she earns working an hour by dividing 600/40 which will give you $15 an hour. From there it asks how much will she earn working 85 hours, so you multiply $15 by the 85 hours so you get 1,275

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.
